Alkylenedithiophosphate derivatives of arsenic(III), antimony(III) and bismuth(III)

Abstract

Tris(alkylenedithiophosphates) of arsenic(III), antimony(III) and bismuth(III), ▪ have been synthesized by the reactions of alkylenedithiophosphoric acids with metal oxides and chlorides and of their ammonium salts with metal chlorides in suitable solvents. Mixed chloride alkylenedithiophosphates of arsenic(III) and antimony(III), ▪ have been obtained by the reactions of metal chlorides with ammonium alkylenedithiophosphates at 1 : 1 and 1 : 2 molar ratios or alternatively by the co-disproportionations reactions of metal chlorides with metal tris(alkylenedithiophosphates) at different (2 : 1 and 1 : 2) molar ratios. These new compounds have been characterized by elemental analyses, molecular weight measurements and spectroscopic (IR, and 1H and 31P NMR) data. Chelated structures with bidentate alkylenedithiophosphate groups have been proposed for all these derivatives.
