Abstract
Ligand-exchange reactions on a mangana(II)cyclopentasilane complex that contains two THF ligands with aryl isocyanides led to the formation of manganese(0) bis(η2-disilene) complexes via a retrocyclization. In stark contrast, ligand-exchange reactions with CNtBu, an N-heterocyclic carbene, or pyridine-based ligands furnished manganese(II) complexes wherein the manganacyclopentasilane framework remained intact. The thermolysis of the obtained bis(η2-disilene) complex in the presence of mesityl isocyanide led to the formation of a cyclotetrasilane via the formal dimerization of the two η2-disilene moieties. The insertion of a mesityl isocyanide into the Mn-Siβ bond results in the formation of a manganese(II) complex supported by a [SiCSi]-type tridentate ligand scaffold.

Abstract
![]()
Utilizing a choice
of α,ω-oligosilanylene diides, it
is possible to synthesize a number of heterocyclosilanes with heteroelements
of calcium, yttrium, and iron by metathesis reactions with respective
metal halides CaI2, YCl3, and FeBr2. 29Si NMR spectroscopic analysis of the calcacyclosilanes
suggests that these compounds retain a strong oligosilanylene dianion
character, which is more pronounced than in the analogous magnesacyclosilanes.
As the electronegativity of calcium lies between potassium and magnesium,
silyl calcium reagents should be considered as building blocks with
an attractive reactivity profile. Reaction of a 1,4-oligosilanylene
diide with YCl3 gave the five-membered yttracyclosilane
as an ate-complex with two chlorides still attached to the yttrium
atom. Reaction of the obtained compound with two equivalents of NaCp
led to another five-membered yttracyclosilane ate-complex with an
yttracene fragment. When using a dianionic oligosilanylene ligand
containing a siloxane unit, the siloxane oxygen acted as an additional
coordination site for Ca and Y. When the same ligand was used to prepare
a cyclic 1-ferra-4-oxatetrasilacyclohexane, an analogous transannular
interaction between the iron and oxygen atoms is missing. Reactions of some α,ω-oligosilanylene
diides
with CaI2, YCl3, and FeBr2 allow
convenient access to metallocyclosilanes with Ca, Y, and Fe as heteroatoms.
The calcium and yttrium compounds resemble previously prepared magnesacyclosilanes,
retaining a strong silanide character. The only related compounds
to the described ferracyclosilanes are acyclic examples.

Abstract
Synthesis of a number of disiloxane containing cyclo- and bicyclooligosilanes is described starting from the dipotassium 1,5-oligosiloxanylene diide derived from 1,3-bis[tris(trimethylsilyl)silyl]tetramethyldisiloxane. In addition, the use of this particular fragment as ligand for zinc and group 4 metallocene complexes was studied. Both types of compounds exhibit marked structural differences compared to related compounds containing Si-Si-Si units instead of the Si-O-Si fragment.

Abstract
![]()
The reaction of the potassium 1,3-trisilanediide
Me2Si[Si(Me3Si)2K]2 with
SmI2 and YbI2 was found to give the respective
disilylated complexes Me2Si[Si(Me3Si)2]2Sm·2THF and Me2Si[Si(Me3Si)2]2Yb·2THF. Desolvation of coordinated solvent
molecules in these complexes made their handling difficult. However,
using a number of functionalized silanide ligands, complexes with
a diminished number or even no coordinated solvent molecules were
obtained ((R3Si)2Ln(THF)x (x = 0–3)). The structures of all
new lanthanide compounds were determined by X-ray single-crystal structure
analysis. NMR spectroscopic analysis of some Yb–silyl complexes
pointed at highly ionic interactions between the silyl ligands and
the lanthanides. This bonding picture was supported by DFT calculations
at the B3PW91/Basis1 level of theory. Detailed theoretical analysis
of a disilylated Eu(II) complex suggests that its singly occupied
molecular orbitals (SOMOs) are very close in energy to the ligand
silicon lone pairs (HOMO), and SQUID magnetometry measurements of
the complex showed a deviation from the expected behavior for a free
Eu(II) ion, which might be due to a ligand–metal interaction. Utilizing a number of functionalized silanides, disilylated Ln(II)
complexes with a diminished number or even no coordinated solvent
molecules were obtained.

Abstract
Most known silatrane chemistry is concerned with examples where the attached silatrane substituent atom is that of an element more electronegative than silicon. The current study features silylated silatranes with a range of electropositive elements attached to the silyl group. The resulting compounds show different degrees of electron density on the silatrane-substituted silicon atom. This directly affects the Si-N interaction of the silatrane which can be monitored either by 29Si NMR spectroscopy or directly by single crystal XRD analysis of the Si-N distance. Within the sample of study the Si-N distance is increased from 2.153 to 3.13 Å. Moreover, the bis(trimethylsilyl)silatranylsilyl unit was studied as a substituent for disilylated germylene adducts.

Abstract
Oligosilanes with attached silatranyl units were obtained by reactions of potassium oligosilanides with a silatranyl triflate. Interaction between Si and N atoms was observed in the 29Si NMR spectra (upfield-shifted SiO3 resonances) and in the solid-state structures (Si-N distances between 2.29 and 2.16 Å). The Si-N interaction can be "switched off" either by protonation of the nitrogen lone pair or by potassium silanide formation caused by trimethylsilyl group cleavage in the presence of potassium tert-butoxide.

Abstract
![]()
Complexes featuring lanthanide silicon
bonds represent a research area still in its infancy. Herein, we report
a series of Cp-free lanthanide (+II) complexes bearing σ-bonded
silyl ligands. By reactions of LnI2 (Ln = Yb, Eu, Sm) either
with a 1,4-oligosilanyl dianion [K-Si(SiMe3)2SiMe2SiMe2Si(SiMe3)2-K)] (1) or with 2 (Me3Si)3SiK (3) the corresponding neutral metallacyclopentasilanes
({Me2Si(Me3Si)2Si}2)Ln·(THF)4 (Ln = Yb (2a), Eu (2b), Sm (2c)), or the disilylated complexes ({Me3Si}3Si)2Ln·(THF)3 (Ln = Yb (4a), Eu (4b), Sm (4c)), were selectively
obtained. Complexes 2b, 2c, 4b, and 4c represent the first examples of structurally
characterized Cp-free Eu and Sm complexes with silyl ligands. In both
series, a linear correlation was observed between the Ln–Si
bond lengths and the covalent radii of the corresponding lanthanide
metals. Density functional theory calculations were also carried out
for complexes 2a–c and 4a–c to elucidate the bonding situation between
the Ln(+II) centers and Si. By reactions of
LnI2 (Ln = Yb, Eu, Sm) with oligosilanyl anions or dianions,
either neutral disilylated complexes or metallacyclopentasilanes were
obtained.

Abstract
By reactions of magnesium oligosilanides with SbCl3, a number of oligosilanylated antimony compounds were obtained. When oligosilanyl dianions were used, either the expected cyclic disilylated halostibine was obtained or alternatively the formation of a distibine was observed. Deliberate formation of the distibine from the disilylated halostibine was achieved by reductive coupling with C8K. Computational studies of Sb-Sb bond energies, barriers of pyramidal inversion at Sb, and the conformational behavior of distibines provided insight for the understanding of the spectroscopic properties.
