摘要：

The reaction of silicon tetraacetate with a tripodal hexadentate ligand (H3L = 1,1,1-tris(N-salicylideneaminomethyl)ethane) afforded the colorless [Si(L)](+) complex. The X-ray analysis of the complex revealed that the Si-N bond distance, av. 1.926(2) Angstrom, is much longer than the Si-O bond distance, av. 1.723(2) Angstrom. The complex is stable toward hydrolysis and could be optically resolved by fractional crystallization of the diastereomeric salt with (-)-dibenzoyl-L-tartaric acid.
