pentacoordinate silicon(IV) complexes with a SiO3NC, SiO2SNC, SiO2SeNC, SiO2N2C, SiOSN2C, or SiOSeN2C skeleton was synthesized and structurally characterized by multinuclear NMR spectroscopy in the solid state and in solution and by single-crystal X-ray diffraction. The compounds studied contain a tridentate dianionic O,N,O or N,N,O ligand, an anionic PhX ligand (X = O, S, Se), and a phenyl group.
合成了一系列具有 SiO3NC、SiO2SNC、SiO2SeNC、SiO2N2C、SiOSN2C 或 SiOSeN2C 骨架的中性五配位硅 (IV) 配合物,并通过固态和溶液中的多核 NMR 光谱以及单晶 X 射线衍射对其结构进行了表征. 研究的化合物包含三齿双阴离子 O,N,O 或 N,N,O 配体、阴离子 PhX 配体 (X = O、S、Se) 和苯基。将这些硅 (IV) 配合物的结构、NMR 光谱参数和化学性质与含有三齿双阴离子 S,N,O 配体而不是 O,N,O 或 N,N,O 配体的相关化合物进行了比较.
