摘要
标题中的 SiIV 复合物 C16H21NO3Si 是由一个与硅环己烷单元结合的三叉二阴希夫碱配体构成的。五配位的 SiIV 原子的配位几何形状是一个扭曲的三叉二棱锥。配合物中硅环己烷环的存在导致 SiIV 原子与希夫碱配体的 N 原子和烷基-C 原子的配位几何形状不同寻常，位于三叉二棱锥的顶端位置。在亚胺键处的甲基出现了紊乱，H 原子有两种取向[主要取向 = 0.55 (3)]。在晶体中，C-H...O 相互作用存在于平行于 ab 平面的波纹状分子层中。
The coordination geometry of the pentacoordinated SiIV atom in the title complex is a distorted trigonal bipyramid.
The title SiIV complex, C16H21NO3Si, is built up by a tridentate dinegative Schiff base ligand bound to a silacyclohexane unit. The coordination geometry of the pentacoordinated SiIV atom is a distorted trigonal bipyramid. The presence of the silacyclohexane ring in the complex leads to an unusual coordination geometry of the SiIV atom with the N atom from the Schiff base ligand and an alkyl-C atom in apical positions of the trigonal bipyramid. There is a disorder of the methyl group at the imine bond with two orientations resolved for the H atoms [major orientation = 0.55 (3)]. In the crystal, C—H⋯O interactions are found within corrugated layers of molecules parallel to the ab plane.
