Abstract

A stable silagermene, 1,1‐bis(tri‐tert‐butylsilyl)‐2,2‐bis(2,4,6‐trimethylphenyl)silagermene, was synthesized by the reaction of dilithiosilane (^t^Bu~3~Si)~2~SiLi~2~ with dichlorodimesitylgermane. Its structure was determined by spectroscopic data and X‐ray crystallography, which showed the SiGe length to be 2.2769(8) Å. The silagermene underwent isomerization at 100ˆC to form the corresponding symmetrically substituted isomer (E)‐1,2‐bis(tri‐tert‐butylsilyl)‐1,2‐bis(2,4,6‐trimethylphenyl)silagermene. © 2008 Wiley Periodicals, Inc.

## Abstract The preparation of a family of dinuclear monocyclopentadienyl imidoniobium and ‐tantalum complexes was achieved by two different synthetic routes. The diimido complexes [{M(Cp′)Cl~2~}~2~(μ‐1,__i__‐NC~6~H~4~N)] [Cp′ = η^5^‐C~5~H~4~SiMe~3~, M = Nb, __i__ = 4 (1); Cp′ = η^5^‐C~5~H~4~SiMe~3
