Triphenylantimony reacts with dialkyl (or alkylenyl) dithiophosphoric acids in 1:1 and 1:2 molar ratio to form complexes of the types Ph3-n Sb[S2P(OR)2]n and Ph3-nSb[S2POGO]n (R

Bis(dialkyl dithiophosphate) derivatives of the type PhM[S2P(OR)2]2 [M = As(III), Sb(III); R = Et, n-Pr, i-Pr, Ph] have been prepared and characterized by elemental analyses and molecular weight determinations. IR and NMR (1H, 13C, 31P) spectral data have been used to investigate plausible structures of these complexes, and their fragmentation pathway has been suggested on the basis of mass spectral data. The crystal structures of PhM[S2P(O-i-Pr)2]2, M = Sb(III) (1) and As(III) (2), have been determined at room temperature by using single-crystal counter data. The crystals are isomorphous with the space group P21/c, Z = 4, and unit cell dimensions a = 12.451 (2) ?, b = 26.681 (6) ?, c = 9.026 (4) ?, and β = 109.70 (2)° for 1 and a = 12.454 (6) ?, b = 26.693 (9) ?, c = 8.901 (5) ?, and β = 109.44 (4)° for 2. The structures were refined by using full-matrix least-squares techniques using 2785 statistically significant reflections for 1 and 878 reflections for 2. The dithiophosphate ligands chelate the central atom with asymmetric M-S bonds (1, 2.5 and 3.1 ?; 2, 2.3 and 3.1 ?) so that the overall geometry is octahedral with a nonbonded pair of electrons occupying an axial position trans to the phenyl group.
