Mixed acetate alkylene dithiophosphates of arsenic(III) and antimony(III)

Abstract

Replacement reactions of arsenic(III) and antimony(III) acetates with alkylene dithiophosphoric acids in stoichiometric ratios yield mixed complexes, M(OAc)_3-x(S₂POGO) _x where M = As or Sb, x = 1 or 2 and G = -CH₂CMe₂CH₂-, -CH₂CEt₂CH ₂-, -CMe₂CMe₂-, and -CHMeCHMe-). These derivatives are hydrolizable, yellow/orange powders with varying solubilities in organic solvents. IR and NMR (¹H, ¹³C and ³¹P) studies indicate bi- arid uni-dentate behaviour of dithiophosphate and acetate moieties, respectively, in these complexes.
