Treatment of [2-(dimethylamino)phenyl]silane (8) with 2 molar equivs of benzene-1,2-dithiol or 2-mercaptoacetic acid yields bis[benzene-1,2-dithiolato(2−)][2-(dimethylammonio)phenyl]silicate (6) and [2-(dimethylammonio)phenyl]bis[2-mercaptoethanoato(2−)-O,S]silicate (7), respectively. The zwitterionic λ5Si-silicates were structurally characterized by solid-state NMR spectroscopy (13C, 15N, 29Si) and single-crystal X-ray diffraction. Compound 6 is the first zwitterionic λ5Si-silicate with Si−S bonds that contains a square-pyramidal Si-coordination polyhedron.
