A series of novel neutral hexacoordinate silicon(IV) complexes with SiO(2)N(4) skeletons (compounds 4-8) was synthesized and structurally characterized by single-crystal X-ray diffraction and solid-state NMR spectroscopy ((13)C, (15)N, (29)Si). The silicon(IV) complexes each contain two bidentate monoanionic O,N Schiff base ligands and two cyanato-N or thiocyanato-N ligands. Compounds 4-8 were prepared from Si(NCO)(4) or Si(NCS)(4), whereby the complex formation involved some unexpected chemical transformations of the ligands.
合成了一系列具有SiO(2)N(4)骨架的新型中性六配位硅（IV）配合物（化合物4 - 8），并通过单晶X射线衍射和固态核磁共振光谱（(13)C、(15)N、(29)Si）对其进行了结构表征。每个硅（IV）配合物都包含两个双齿单阴离子O,N席夫碱配体和两个氰酸根-N或硫氰酸根-N配体。化合物4 - 8由Si(NCO)(4)或Si(NCS)(4)制备，其中配合物的形成涉及配体的一些意外化学转化。
