Abstract: | O,O-Alkylenedithiophosphates of diorganotin(IV) of the type R2SnSP(S)O2G]2 (R = Me, Et, n-Bu, Ph; G = CH2CMe2CH2, CMe2CMe2, CMe2CH2CHMe) have been synthesized by the reactions of diorganotin(IV) dichlorides with ammonium O,O-alkylenedithiophosphates or that of diorganotin(IV) oxides with O,O-alkylenedithiophosphoric acids in 1:2 molar ratio in benzene. These new complexes are white solids which are soluble in common organic solvents and are monomeric in refluxing benzene; and they have been characterized by elemental analysis and by different spectroscopic (IR, 1H, 13C, 31P and 119Sn NMR) studies, on the basis of which a six coordinated octahedral structure has been suggested in solution. |
