AbstractThe structure of [PtS4(Ph2PCH2CH2PPh2)] has been determined by single-crystal X-ray techniques using diffractometer data. The compound crystallises in the monoclinic space group P21/a, with four molecules in a cell of dimensions a = 9.736(3), b = 30.964(7), c = 9.806(5) Å, and β = 117.81(4)°. Least-squares refinement of the structure led to a final R value of 0.043 using 3 292 observed intensities. The complex is approximately square planar and the tetrasulphido-ligand behaves as a dianionic chelating ligand. The resultant PtS4 ring adopts an approximately C2 conformation. The central S-S bond is 0.046 Å shorter than the outer S-S bonds [average 2.058(15) Å]. A molecular orbital analysis of the bonding in this and related complexes has been used to interpret this geometric feature.
