Abstract
The newly prepared and fully characterized stibenium and bismuthenium ions [Rind MesE]+ (E=Sb, Bi; Rind =dispiro[fluorene-9,3'-(1',1',7',7'-tetramethyl-s-hydrindacen-4'-yl)-5',9''-fluorene) were rigorously compared to the previously communicated phosphenium and arsenium ions (E=P, As) as well as the bis(m-terphenyl) pnictogenium ions [(2,6-Mes2 C6 H3 )2 E]+ (E=Sb, Bi). It is demonstrated that the choice of the aryl substituents dramatically effects the molecular structures (e. g. the primary E-C bond lengths) and the electronic structures (e. g. the energy of the LUMOs).

Abstract
Abstract
This review summarises the experimental and structural knowledge on polycyclic phosphanes, with a focus on bicyclic and tricyclic phosphanes, as they have not only been the most studied in the last 25 years, but also show the greatest diversity in terms of constitutional isomerism and structural motifs. Moreover, only polycyclic phosphanes that have p-block substituents at all free valences are discussed.

Weis P, Röhner DC, Prediger R, Butschke B, Scherer H, Weber S, Krossing I. First experimental evidence for the elusive tetrahedral cations [EP 3] + (E = S, Se, Te) in the condensed phase. Chem Sci 2019; 10:10779-10788. [PMID: 32055385 PMCID: PMC7006506 DOI: 10.1039/c9sc03915e] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Accepted: 10/06/2019] [Indexed: 11/21/2022] Open
Abstract
Condensed phase access to the unprecedented tetrahedral cations [EP3]+ (E = S, Se, Te) was achieved through the reaction of ECl3[WCA] with white phosphorus ([WCA]- = [Al(ORF)4]- and [F(Al(ORF)3)2]-; -RF = -C(CF3)3). Previously, [EP3]+ was only known from gas phase MS investigations. By contrast, the reaction of ECl3[A] with the known P3 3- synthon Na[Nb(ODipp)3(P3)] (enabling AsP3 synthesis), led to formation of P4. The cations [EP3]+ were characterized by multinuclear NMR spectroscopy in combination with high-level quantum chemical calculations. Their bonding situation is described with several approaches including Atoms in Molecules and Natural Bond Orbital analysis. The first series of well-soluble salts ECl3[WCA] was synthesized and fully characterized as starting materials for the studies on this elusive class of [EP3]+ cations. Yet, with high [ECl3]+ fluoride ion affinity values between 775 (S), 803 (Se) and 844 (Te) kJ mol-1, well exceeding typical phosphenium ions, these well-soluble ECl3[WCA] salts could be relevant in view of the renewed interest in strong (also cationic) Lewis acids.

Abstract
The chemical reaction of di-lithium N,N'-di( t but-yl)-Si,Si-di-phenyl-silanedi-amide and PCl3 yielded an off-white solid. Sublimation of the crude product under reduced pressure at elevated temperature gave colourless prismatic crystals of the title compound, C20H28ClN2PSi, which crystallizes in the non-centrosymmetric monoclinic space group Cc. The asymmetric unit of the crystal structure contains one mol-ecule and it is dominated by the central SiN2P four-membered ring, which is almost planar with a mean deviation of the atoms from the best plane of 0.014 Å. The angles between the plane defined by the silicon atom and the two nitro-gen atoms and the best planes of the Si-phenyl groups are 85.1 (2) and 77.4 (2)°, with the tilt of the phenyl rings in the opposite direction. Both tert-butyl groups suffer from a two-position rotational disorder with site occupancies of 0.752 (6)/0.248 (6) and 0.878 (9)/0.122 (9). The P-Cl bond [2.2078 (17) Å] is remarkably elongated compared to the P-Cl distance in PCl3 [2.034 Å; Galy & Enjalbert (1982). J. Solid State Chem. 44, 1-23].

Abstract
Bis(amidodimethyl)disiloxane ligands derived from O{SiMe2N(H)R}2 (abbreviated as (NONR)H2) are a stable support for neutral and cationic bismuth compounds. Attempts to extend the series Bi(NONR)Cl (R = Ar = 2,6-iPr2C6H3; R = tBu) to include compounds where R = Ar' = 2,6-Me2C6H3 were complicated by concomitant formation of the bimetallic compound {Bi(NONAr')}2(μ-NONAr'). Compounds containing [Bi(NONR)]+ cations were obtained from reactions with group 13 chlorides MCl3 (M = Al, Ga). X-ray crystallographic analysis showed intermolecular interactions with the [MnCl(3n+1)] anion.
