摘要
Organotin(IV) complexes of the type, R2Sn[S2P(OR')(2)](2) (where R = Me, n-Bu and R' = o-, m-, p-C6H4Me) have been obtained by the reaction of Me2SnCl2 or n-Bu2SnCl2 with ammonium salts of the corresponding O,O'-ditolyl dithiophosphates on stirring in benzene and have been characterized by elemental analysis and IR, H-1, C-13, P-31 and Sn-119 NMR spectroscopy. Trends in data are discussed. The crystal structures of Me2Sn[S2P(OC6H4Me-o)(2)](2) and n-Bu2Sn[S2P(OC6H4Me-o)(2)](2) are reported. The environment around the tin atom in both molecules may be described as having skew-trapezoid bipyramidal geometry. Copyright (c) 2007 John Wiley & Sons, Ltd.
