Abstract The synthetic, spectroscopic and biological studies of some diorganosilicon (IV) complexes derived from fluoroimines having NS and NO donor systems have been undertaken. The fluoroimines were prepared by the condensation of 2-Fluorobenzaldehyde and 1-(2-Fluorophenyl)-ethanone with hydrazinecarbothioamide and hydrazinecarboxamide. These imines, on interaction with diorganosilicon (IV) chlorides, ...
