The prepapration, and first comprehensive spectroscopic and structural characterization of octahedral trichlorosilane adducts HSiCl3(Rpy)2 with R = H, 4-CH3, 4-C6H5, 3-Br, 4-CHCH2, 4-C2H5, 4-C(CH3)3 and 4-N(CH3)2 is reported. The products are surprisingly stable in the solid state and easily obtained in high yield. Single-crystal X-ray diffraction analysis of HSiCl3(3-Brpy)2 revealed relatively short

C2H5、4-C( )报告了 3 和 4-N( )2。产物在固态下出人意料地稳定并且容易以高产率获得。HSiCl3(3-Brpy)2 的单晶 X 射线衍射分析显示,Si-Cl 键相对较短(218-223 pm),而 Si-N 键(约 198 pm)仅比相应的 H2SiCl2 略长(Rpy)2 加合物。仅在升高的温度下在极性溶剂中观察到歧化反应。 (© Wiley-
