Jh. Li et al., The theoretical studies of interaction of transition-metals with silylene ligands (I) - Ab initio study of MSiH2+, CHEM J CH U, 20(12), 1999, pp. 1906-1909
The HF/6-311+G* basis set was used to study the complexes of silylene,(SiH2
)-Si-1, with first-row transition-metal ions. The MSiH2 can be regarded as
the result of coordination of (SiH2)-Si-1 with metal ions, and are of copla
nar structure. Their M = Si bonds are obviously of double bond characterist
ic. M = Si bond dissociation energies appear in periodic trends from Sc to
Cu, and have an approximate linear relationship with metal ion promotion en
ergies.
