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(S₂ )_x where M = As or Sb, x = 1 or 2 and G = –CH₂CMe₂CH₂–,–CH₂CEt₂CH₂–, –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.
