Synthesis and Crystal Structure of cis-meso-1, 3-Bis(propylsulfinyl)propanedichloroplatinum(Ⅱ)

摘要

A mononuclear complex, cis-[meso-1, 3-bis(propylsulfinyl)propane]- dichloroplatinum(Ⅱ) (Pt(C9H20O2S2)Cl2) 1, has been prepared and structurally characterizated by single-crystal X-ray diffraction. The crystal belongs to orthorhombic system, space group Pna21 with a = 22.800(3), b = 11.7662(13), c = 5.8115(6) ?, V = 1559.0(3) ?3, Mr = 490.36, Dc = 2.089 g/cm3, Z = 4, F(000) = 936, ( (MoK() = 9.596 mm-1 and ( = 0.71073 ?. The structure was refined to R = 0.0204 and wR = 0.0473 for 2703 reflections with I > 2σ(I). It is revealed that the central Pt(Ⅱ) ion in the title complex is bonded to two Cl atoms in a cis-configuration and two S atoms of the ligand to form the coordination geometry deviating slightly from the square planar.
