摘要
The crystals of the title complex, cis-dichloro-(tetrakis(methylthio)-ethylene) palladium(Ⅱ) (C6H12Cl2PdS4, Mr = 389.70 ) have been synthesized and analyzed structurally by single-crystal X-ray diffraction. The crystal belongs to the triclinic system, space group P with a = 8.211(1), b = 8.443(1), c = 10.134(2) ? a = 78.34(1), b = 89.02(2), g = 71.06(1)? V = 649.9(2) 3, Z = 2, Dc = 1.991 g/cm3, m (MoKa) = 2.437 mm-1, F(000) = 384, R = 0.0246 and Rw = 0.0621 for 2417 observed reflections with I > 2s(I). The X-ray crystal structure analysis revealed that the palladium (Ⅱ) is coordinated to two chloride anions and one chelate ligand TMTE in a quasi-square coordination geometry. Two molecules pack in face to face forming a dimmer structure with PdPd distance 3.424 ? Detailed discussions for the structure data of the complex were given by comparing with that of the free TMTE.
