Metal And Organometal Complexes Of Oxy And Thiophosphorus Acids .9. O,O'-Alkylene Dithiophosphates Of Zinc And Cadmium

Bis(alkylene dithiophosphates)of the type M[S2POGO]2, (where M = Zn, Cd; G = -CH2CMe2CH2-,-CMe2CMe2-,-CHMeCHMe-,-CMe2CH2CHMe-,-CH2CEt2CH2-) obtained by the reaction of MX2 [where X = Cl, CH3COO, S2P(OR)2 (R = Et, Pr(i))] with alkylene dithiophosphoric acids or their ammonium salts, are white or yellow colored solids. insoluble in common organic solvents but are soluble in DMSO, DMF and pyridine. These have been characterized on the basis of elemental analyses, molar conductivity, IR and NMR (H-1 and P-31) spectral studies which reveal the bidentate behaviour of the dithiophosphate moiety.
