METAL AND ORGANOMETAL COMPLEXES OF OXY AND THIOPHOSPHORUS ACIDS PART IX: O,O'-ALKYLENE DITHIOPHOSPHATES OF ZINC AND CADMIUM

Abstract

Bis(alkylene dithiophosphates) of the type M[S₂ POGO]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')] 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 (¹H and ³¹P) spectral studies which reveal the bidentate behaviour of the dithiophosphate moiety.

Key Words:

• O.O'-alkylene dithiophosphates
