Synthesis and Crystal Structure of cis-[meso-1, 3-Bis(propylsulfinyl)propane]dichloroplatinum(Ⅱ)

【Abstract】 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) ?, Mr = 490.36, Dc = 2.089 g/cm3, Z = 4, F(000) = 936, m (MoKa) = 9.596 mm-1 and l = 0.71073 ? The structure was refined to R = 0.0204 and wR = 0.0473 for 2703 reflections with I > 2(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.更多还原
