Organotin(IV) complexes of the type, R 2 Sn[S 2 P(OR′) 2 ] 2 (where R = Me, n ‐Bu and R′ = o ‐, m ‐, p ‐C 6 H 4 Me) have been obtained by the reaction of Me 2 SnCl 2 or n ‐Bu 2 SnCl 2 with ammonium salts of the corresponding O , O ′‐ditolyl dithiophosphates on stirring in benzene and have been characterized by elemental analysis and IR, 1 H, 13 C, 31 P and 119 Sn NMR spectroscopy. Trends in data are discussed. The crystal structures of Me 2 Sn[S 2 P(OC 6 H 4 Me‐ o ) 2 ] 2 and n ‐Bu 2 Sn[S 2 P(OC 6 H 4 Me‐ o ) 2 ] 2 are reported. The environment around the tin atom in both molecules may be described as having skew‐trapezoid bipyramidal geometry. Copyright © 2007 John Wiley & Sons, Ltd.
