摘要
Syntheses and structures of two novel "doubledecker" silicon complexes [R-Si(o-O-P-OMe-C6H3C(Ph)=N-(CH2)(2)-N=C(Ph)-C6H3-p-OMe-o-O)-CH2-](2) (R = Ph, p-tBu-C6H4-O) with the silicon atoms hexacoordinated by two salen-type tetradentate < OATNO >-chelating ligands are described. Hydrogen bonding between the halves of the bridged complexes as well as with chloroform solvate molecules determines the conformation. Compared with analogous mononuclear silicon complexes these "doubledeckers" show bathochromically shifted Vis-absorption.
