Synthesis and crystal structure of {(PPh(3))AgS2P(OCH(2)Ph)(2)}(2)

A binuclear complex, {(PPh(3))AgS2P(OCH(2)Ph)(2)}(2), has been synthesized and structurally determined using X-ray diffraction. The crystal is triclinic, space group <P(1)over bar>, a = 1.0425(5), b = 1.2902(4), c = 1.3395(3) nm, alpha = 70.96(3)degrees, beta = 103.14 (3)degrees, gamma = 72.25 (4)degrees, V = 1.5114(7) nm(3) and Z=1, the least-squares refinement based on 5633 observed reflections converged to a final R value of 0.079. The molecular structure indicates that the complex is a dimmer, in which two (PPh(3))AgS2P(OCH(2)Ph)(2) units are connected by symmetrical alkyl dithiophosphate bridges. The bonding modes of the two sulfur atoms of dithiophosphate ligand are very different: one bridges two Ag atoms with two Ag-S bond lengths of 0.2978 (5) and 0.2528(2) nm, while the other only bonds to one Ag atom with a Ag-S bond length of 0.2590(3) nm. Ag is tetrahedrally coordinated with three S atoms and a P atom from PPh(3).
