Complexes of the cis-[Pt(Me2SO)LCl2] series (L = Me2SO, Me2S, C2H4, MeCN, PhCH2CN, PhCN, C5H5N, 2Me-C5H4N and NH3) were prepared by known methods and characterized by IR and H-1, C-13H-1}, Pt-195H-1} NMR spectra. Structures of cis-[Pt(Me2SO)(C2H4)Cl2] and cis-[Pt(Me2SO)(PhCH2CN)Cl2] were determined by X-ray analysis. cis-[Pt(Me2SO((C2H4)Cl2] Crystallizes in the orthorhombic space group Pmnb. The unit cell parameters are a = 8.200(1), b = 12.924(3), c = 8.574(1) angstrom, V = 908.7(3) angstrom 3, rho-calc = 2.72 gcm-3, Z = 4. cis-[Pt(Me2SO)(PhCH2CN)Cl2] crystallizes in the monoclinic space group P2(1)/n. The unit cell parameters are: a = 12.223(4), b = 16.605(4), c = 6.779(2) angstrom, gamma = 91.10(2)-degrees, V = 1375.6(7) angstrom 3, rho-calc = 2.23 g cm-3 , Z = 4. On the basis of the X-ray structure data cis- and trans-influence of C2H4 and PhCH2CN ligands were determined.
