Samenvatting

Donor-acceptor substituted diphenylsilanes have been synthesized because of their nonlinear optical properties. The crystal and molecular structure of disilanes having a dimethylamino donor and a sulfonyl containing acceptor are described for the first time. These molecules have a trans-type conformation. The geometries of the acceptors reflect their distinct electron-withdrawing character. Strong electron conjugation between the phenyl ring and the dimethylamino donor, which is almost sp2 hybridized, is indicated. The structural data form a useful basis for the analysis of molecular properties, obtained experimentally or predicted by calculations.
