Abstract
Organometallic molecules are promising for molecular electronic devices due to their potential to improve electrical conductance through access to complex orbital covalency that is not available to light-element organic molecules. However, studies of the formation of organometallic monolayers and their charge transport properties are scarce. Here, we report the cluster formation and charge transport properties of gold-triarylbismuthane-gold molecular junctions. We found that triarylbismuthane molecules with -CN anchoring groups form clusters during the creation of self-assembled submonolayers. This clustering is attributed to strong interactions between the bismuth (Bi) center and the nitrogen atom in the -CN group of adjacent molecules. Examination of the influence of -NH2 and -CN anchoring groups on junction conductance revealed that, despite a stronger binding energy between the -NH2 group and gold, the conductance per molecular unit (i.e., molecule for the -NH2 group and cluster for the -CN group) is higher with the -CN anchoring group. Further analysis showed that an increase in the number of -CN groups from one to three within the junctions leads to a decrease in conductance while increasing the size of the cluster. This demonstrates the significant effects of different anchoring groups and the impact of varying the number of -CN groups on both the charge transport and cluster formation. This study highlights the importance of selecting the appropriate anchoring group in the design of molecular junctions. Additionally, controlling the size and formation of clusters can be a strategic approach to engineering charge transport in molecular junctions.

Abstract
In this work, we report the preparation of multiple interpnictogen chain compounds with three consecutive pnictogen atoms and terminal Ar2 Bi fragments (Ar=Ph, Mes). Symmetrical compounds of the form Ar2 Bi-E(tBu)-Bi2 Ar (1: Ar=Ph, E=P; 2: Ar=Ph, Mes, E=As) as well as ternary interpnictogen compounds of the form Ar2 Bi-E1 (tBu)-E2 tBu2 (Ar=Ph, Mes; 4: E1 =P, E2 =As; 5: E1 =P, E2 =Sb; 6: E1 =As, E2 =P) were prepared. The decomposition in solution at room temperature and under the influence of light was studied for compounds 1-6. The reactivity of 1Ph and 2Ph with the small N-heterocyclic carbene 1,3,4,5-tetramethylimidazol-2-ylidene (Me2 IMe) was also studied. In the case of 1Ph , the formation and consecutive decomposition of Me2 IMe=PtBu (8) was observed in solution. Hence, it was shown that 1Ph can react as a "masked phosphinidene". In the case of 2Ph , no reaction with Me2 IMe was observed. All isolated compounds were analysed by NMR and IR spectroscopy, mass spectrometry, elemental analysis and single-crystal X-ray diffraction.

Abstract
Multiple interpnictogen compounds with covalent single bonds between a diarylbismuth fragment and all lighter pnictogens were prepared from the corresponding diarylhalido bismuthanes. The aminobismuthanes Ph2BiNMe2 (1) and Mes2BiNMe2 (2) (Mes = 2,4,6-trimethylphenyl-) have been obtained via a salt metathesis reaction and compound 2 was successfully reacted with tBuNH2 in a condensation reaction to yield Mes2BiNHtBu (3). The bismuthanyl phosphanes Ar2BiPtBu2 (Ar = Ph: 4 and Ar = Mes: 5) and arsanes Ar2BiAstBu2 (Ar = Ph: 8 and Ar = Mes: 9) were also obtained via salt metathesis. Through a trimethylsilyl halide abstraction reaction of the diaryl halido bismuthanes and EtBu(SiMe3)2 (E = P and As), the bismuthanyl phosphanes Ar2BiPtBu(SiMe3) (Ar = Ph: 6; Ar = Mes: 7) and the arsanes Ar2BiAstBu(SiMe3) (Ar = Ph: 10; Ar = Mes: 11) have been prepared. Bismuthanyl stibanes were accessed via a condensation reaction of Mes2SbH with 1 or 2, respectively. The compound Ph2BiSbMes2 (12), which has different substituents at the bismuth and antimony atoms, was isolated and fully characterised. In contrast, the isolation of Mes2BiSbMes2 (13) was not possible due to a dynamic equilibrium with Mes4Bi2 and Mes4Sb2 which was investigated via low-temperature 1H-NMR spectroscopy in solution. The isolated compounds with a single bond between bismuth and the heavy pnictogens arsenic and antimony are rare examples of their kind. All isolated compounds (1-12) were characterised by NMR and IR spectroscopy, mass spectrometry, elemental analysis and single crystal X-ray diffraction.

Abstract
Highly refractive and X-ray shielding polymer films were prepared by bulk radical copolymerization of diphenylstyrylbismuthine (MStBi) with tristyrylbismuthine (TStBi). For example, a yellow transparent film was obtained by copolymerization of MStBi and TStBi in a ratio of 70:30 (w/w). The refractive index (nD) and radiopacity of the film of these polymers are 1.72 and 1.60 μm-Al/μm-polymer, respectively. These properties are higher than those of the reported bismuth-containing polymers. The thermal stability and flexural module of the polymer films were controllable by the feed ratio of TStBi. The polymer films also exhibited high surface hardness and solvent resistance due to the rigid and cross-linked structure. The chemical and thermal stability and higher refractive index and radiopacity of the polymers suggest the potential applications for X-ray shielding of optical materials with high refractive indices.

Abstract
![]()
A series of cationic
fluorotriarylbismuthonium salts bearing differently
substituted aryl groups (Ar = 9,9-Me2-9H-xanthene, Ph,
Mes, and 3,5-tBu-C6H3) have
been synthesized and characterized. While the presence of simple phenyl
substituents around the Bi center results in a polymeric structure
with three Bi centers in the repeating monomer, substituents at the ortho- and meta-positions lead to cationic
mono- and dinuclear fluorobismuthonium complexes, respectively. Preparation
of all compounds is accomplished by fluoride abstraction from the
parent triaryl Bi(V) difluorides using NaBArF (BArF– = B[C6H3-3,5-(CF3)2]4–). Structural
parameters were obtained via single crystal X-ray diffraction (XRD),
and their behavior in solution was studied by NMR spectroscopy. Trinuclear
and binuclear complexes are held together through one bridging fluoride
(μ-F) between two Bi(V) centers. In contrast, the presence of
Me groups in both ortho-positions of the aryl ring
provides the adequate steric encumbrance to isolate a unique mononuclear
nonstabilized fluorotriarylbismuthonium cation. This compound features
a distorted tetrahedral geometry and is remarkably stable at room
temperature both in solution (toluene, benzene and THF) and in the
solid state.

Abstract
The noncovalent interactions of heavy pnictogens with π-arenes play a fundamental role in fields like crystal engineering or catalysis. The strength of such bonds is based on an interplay between dispersion and donor/acceptor interactions, and is generally attributed to the presence of π-arenes. Computational studies of the interaction between the heavy pnictogens As, Sb and Bi and cyclohexane, in comparison with previous studies on the interaction between heavy pnictogens and benzene, show that this concept probably has to be revised. A thorough analysis of all the different energetic components that play a role in these systems, carried out with state-of-the-art computational methods, sheds light on how they influence one another and the effect that their interplay has on the overall system. Furthermore, the analysis of such interactions leads us to the unexpected finding that the presence of the pnictogen compounds strongly affects the conformational equilibrium of cyclohexane, reversing the relative stability of the chair and boat-twist conformers, and thus suggesting a possible application of tuneable dispersion energy donors to stabilise the desired conformation.

Abstract
A new tripodal C-anionic ligand, 2-{bis(benzothiazolyl)(methoxy)methyl}phenyl (L), was stably generated by the reaction of the ligand precursor (L'), the corresponding bromide (2-BrC6H4)(MeO)C(C7H4NS)2 (C7H4NS = 2-benzothiazolyl), with nBuLi at -104 °C in the presence of TMEDA (N,N,N',N'-tetramethylethylenediamine). The ligand lithium salt reacted with BiCl3 to give a 2 : 1 complex L2BiCl. A 1 : 1 complex LBiCl2 was obtained in good yield by the redistribution reaction between L2BiCl and BiCl3. X-ray diffraction analysis revealed that the ligand L coordinated in an expected κ3-C,N,N' coordination mode in LBiCl2, while it coordinated in κ3-C,N,O and κ2-C,O coordination modes in L2BiCl. The ligand precursor reacted with BiX3 (X = Cl, Br) to give 1 : 1 complexes L'BiX3 and was found to act as a neutral tripodal C(π),N,N-ligand.

Abstract
Three-coordinate cationic bismuth compounds [Bi(diaryl)(EPMe3 )][SbF6 ] have been isolated and fully characterized (diaryl=[(C6 H4 )2 C2 H2 ]2- , E=S, Se). They represent rare examples of molecular complexes with Bi⋅⋅⋅EPR3 interactions (R=monoanionic substituent). The 31 P NMR chemical shift of EPMe3 has been found to be sensitive to the formation of LA⋅⋅⋅EPMe3 Lewis acid/base interactions (LA=Lewis acid). This corresponds to a modification of the Gutmann-Beckett method and reveals information about the hardness/softness of the Lewis acid under investigation. A series of organobismuth compounds, bismuth halides, and cationic bismuth species have been investigated with this approach and compared to traditional group 13 and cationic group 14 Lewis acids. Especially cationic bismuth species have been shown to be potent soft Lewis acids that may prefer Lewis pair formation with a soft (S/Se-based) rather than a hard (O/N-based) donor. Analytical techniques applied in this work include (heteronuclear) NMR spectroscopy, single-crystal X-ray diffraction analysis, and DFT calculations.

Abstract
High-level ab initio calculations using the DLPNO-CCSD(T) method in conjunction with the local energy decomposition (LED) were performed to investigate the nature of the intermolecular interaction in bismuth trichloride adducts with π arene systems. Special emphasis was put on the effect of substituents in the aromatic ring. For this purpose, benzene derivatives with one or three substituents (R=NO2 , CF3 , OCHO, OH, and NH2 ) were chosen and their influence on donor-acceptor interaction as well as on the overall interaction strength was examined. Local energy decomposition was performed to gain deeper insight into the composition of the interaction. Additionally, the study was extended to the intermolecular adducts of arsenic and antimony trichloride with benzene derivatives having one substituent (R=NO2 and NH2 ) in order to rationalize trends in the periodic table. The analysis of natural charges and frontier molecular orbitals shows that donor-acceptor interactions are of π→σ* type and that their strength correlates with charge transfer and orbital energy differences. An analysis of different bonding motifs (Bi⋅⋅⋅π arene, Bi⋅⋅⋅R, and Cl⋅⋅⋅π arene) shows that if dispersion and donor-acceptor interaction coincide as the donor highest occupied molecular orbital (HOMO) of the arene is delocalized over the π system, the M⋅⋅⋅π arene motif is preferred. If the donor HOMO is localized on the substituent, R⋅⋅⋅π arene bonding motifs are preferred. The Cl⋅⋅⋅π arene bonding motif is the least favorable with the lowest overall interaction energy.

Abstract
The role of intramolecular metal⋅⋅⋅π-arene interactions has been investigated in the solid-state structures of a series of main group compounds supported by the bulky amide ligands, [N(tBu Ar≠ )(SiR3 )]- (tBu Ar≠ =2,6-(CHPh2 )2 -4-tBuC6 H2 , R=Me, Ph). The lithium and potassium amide salts showed different patterns of solvation and demonstrated that the SiPh3 substituent is able to be involved in stabilizing the electrophilic metal. These group 1 metal compounds served as ligand transfer reagents to access a series of bismuth(III) halides. Chloride extraction from Bi(N{tBu Ar≠ }{SiPh3 })Cl2 using AlCl3 afforded the 1:1 salt [Bi(N{tBu Ar≠ }{SiPh3 })Cl][AlCl4 ]. This was accompanied by a significant rearrangement of the stabilizing π-arene contacts in the solid-state. Attempted preparation of the corresponding tetraphenylborate salt resulted in phenyl-transfer and generation of the neutral Bi(N{tBu Ar≠ }{SiPh3 })(Ph)Cl.
