Abstract

Triphenylantimony reacts with dialkyl (or alkylenyl) dithiophosphoric acids in 1:1 and 1:2 molar ratio to form complexes of the types Ph_3-h Sb(S₂P(OR)₂]_n and Ph_3-n sb[S₂ ]_n (R = Pr-n, Pr-i, Bu-i; G = -CMe₂CMe₂, -CH₂CMe₂CH₂-, - CMe₂CH₂CHMe-, n = 1,2) by the cleavage of antimony-carbon bonds. The complexes are colourless powdery solids, soluble in common organic solvents, monomeric in nature and have been characterized by various physico-chemical and spectroscopic [IR, NMR (¹H, ¹³C, ³¹P)] techniques.
