The title complex was prepared from the reaction of 1,2-bis(phenylthiomethyl)-benzene L with K2PtCl4 at room temperature and its structure has been determined by single-crystal X-ray diffraction. There exist two independent cis-[1,2-bis(phenylthiomethyl)benzene]dichloroplatinum(Ⅱ) [PtCl2L] molecules without significant structural difference and a molecule of acetonitrile in one crystallographic asymmetric unit. Crystallographic data: triclinic, space group P1-, a = 11.010(3), b = 12.080(3), c = 16.095(4)(A), α = 94.728(5),β = 90.129(5), γ = 99.274(5)°,C2oH18Cl2NPtS2@0.5CH3CN, Mr = 608.98, V = 2105(1) (A)3, Z = 4, Dc = 1.921 g/cm3, μ(Mo-Kα) =7.122 mm-1, F(000) = 1172, R = 0.0503 and wR = 0.0848 for 3929 observed reflections with Ⅰ＞2σ(Ⅰ). The title complex is a neutral molecule in which the central Pt(Ⅱ) ion is four-coordinated with two S-donors of the ligand and two Cl- anions, forming a distorted square planar geometry. In the crystal, there exist two kinds of molecular packing patterns. One [PtCl2L] molecule is connected to the other one through the weak interactions of Pt…Pt, Pt…S and Pt…C1, forming a supramolecular quasi-dimer. The other one complex molecule is connected with the CH3CN molecule by weak Cl…N interaction.
