SYNTHESIS AND CHARACTERIZATION OF THIOLATO-BRIDGED TITANIUM-PLATINUM AND TITANIUM-PALLADIUM HETEROBINUCLEAR COMPLEXES - MOLECULAR-STRUCTUREOF TA(5)-C(5)H(4)SIME(3))(2)TI(MU-SPH)(2)PD(C6F5)(2)]

A series of titanium-platinum and -palladium heterobinuclear compounds with double thiolato bridges, [(eta(5)C(5)H(4)R')(2)Ti(mu-SR)(2)M(C6F 5)(2)] (R' = H, SiMe(3); R = Ph, C6F5; M = Pd, Pt), has been prepared. The crystal structure of ta(5)-C(5)H(4)SiMe(3))(2)Ti(mu-SPh)(2)Pd(C6F 5)(2)] has been established by single-crystal X-ray crystallography: t he complex crystallizes in the monoclinic system in space group P2(1)/ c; a = 10.237 (2) Angstrom; b = 14.635 (3) Angstrom; c = 27.651 (6) An gstrom; beta = 90.83 (2)degrees; Z = 4; and R = 0.056. The titanium at om is in pseudotetrahedral coordination environment, whereas the palla dium is square-planar. The phenyl groups on the sulfur atoms adopt an endo (syn) arrangement with respect to the central Ti-S-2-Pd core.
