Syntheses and structures of two novel “doubledecker” silicon complexes [R-Si(o-O-p-OMe-C6H3- C(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 〈ONNO〉-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.
Ferrocenylsilanes with various functions at silicon (chlorine, vinyl, ethynyl) were prepared and studied by multinuclear magnetic resonance methods (1H, 13C, 29Si NMR spectroscopy). The gasphase geometries of the silanes were optimized by calculations at the B3LYP=6-311+G(d,p) level of theory, and NMR parameters (chemical shifts δ13C, δ29Si, spin-spin coupling constants) were calculated at the same level of theory.
