合成了中性五配位硅（IV）配合物1（SiS 2 ONC骨架）、2（SiSeSONC）、3（SiTeSONC）、6 - 9（SiSe 2 O2 C）、7（SiSe 2 S2 C）和8/10（SiSe 4C），并通过单晶X射线衍射和多核固态和溶液态（6-9除外）核磁共振谱进行了结构表征。通过化合物1-3和6-10的合成，已经证明具有软硫属元素配体原子（S、Se、Te）的五配位硅化合物可以在固态和溶液中稳定。
The neutral pentacoordinate silicon(IV) complexes 1 (SiS2ONC skeleton), 2 (SiSeSONC), 3 (SiTeSONC), 6/9 (SiSe2O2C), 7 (SiSe2S2C), and 8/10 (SiSe4C) were synthesized and structurally characterized by using single-crystal X-ray diffraction and multinuclear solid-state and solution-state (except for 6-9) NMR spectroscopy. With the synthesis of compounds 1-3 and 6-10, it has been demonstrated that pentacoordinate silicon compounds with soft chalcogen ligand atoms (S, Se, Te) can be stable in the solid state and in solution.
