M(CO)5Si6Me11 * 0.5 n-C5H12 (M = Mn, Re) were determined by single crystal X-raydiffraction. The two compounds are isomorphous. Their silicon-silicon bondlengths are compared with those of the parent cyclohexasilane and of other cyclohexasilyl complexes (comprising group 6, 7, 8, and 10 as well as row 3, 4, and 5 transition metals) with respect to silicon-silicon bond activation.
通过单晶X射线衍射测定过渡金属环己甲硅烷基络合物M(CO)5 Si 6 Me 11 * 0.5 n -C 5 H 12(M = Mn,Re)的分子结构。这两种化合物是同构的。就硅-硅键而言,将它们的硅-硅键长与母体环己硅烷和其他环六甲硅烷基络合物(包括第6、7、8和10组以及第3、4和5行过渡金属)的长度进行比较激活。
Zur darstellung von permethylierten cyclosilanylalkalimetall-derivaten
A simple way for the preparation of undecamethylcyclohexasilanylalkalimetal compounds is described by the reaction of dodecamethylcyclohexasilane with alkalimetal alcoholats in glyme solvents. Reactions of other cyclosilanes are also discussed. Some reactions of undecamethylcyclohexasilanylpotassium with element-halogen derivates and inorganic acids are described.
