Description
Summary:lp;&-5q;1The reactions of [Tl2{S2CC{C(O)Me}2}] n with [MCl2L2] (1:1) or with [MCl2(NCPh)2] and PPh3 (1:1:2) give complexes [M{η2-S2CC{C(O)Me}2}L2] [M = Pt, L2 = 1,5-cyclooctadiene (cod) (1); L2 = bpy, M = Pd (2a), Pt (2b), L = PPh3, M = Pd (3a), Pt (3b)] whereas with MCl2 and QCl (2:1:2) anionic derivatives Q2[M{η2-S2CC{C(O)Me}2}2] [M = Pd, Q = NMe4 (4a), Ph3PNPPh3 (PPN) (4a‘), M = Pt, Q = NMe4 (4b)] are produced. Complexes 1 and 3 react with AgClO4 (1:1) to give tetranuclear complexes [{ML2}2Ag2{μ2,η2-(S,S‘)-{S2CC{C(O)Me}2}2}](ClO4)2 [L = PPh3, M = Pd (5a), Pt (5b), L2 = cod, M = Pt (5b‘)], while the reactions of 3 with AgClO4 and PPh3 (1:1:2) give dinuclear [{M(PPh3)2}{Ag(PPh3)2}{μ2,η2-(S,S‘)-{S2CC{C(O)Me}2}}]ClO4 [M = Pd (6a), Pt (6b)]. The crystal structures of 3a, 3b, 4a, and two crystal forms of 5b have been determined. The two crystal forms of 5b display two {Pt(PPh3)2}{μ2,η2-(S,S‘)-{S2CC{C(O)Me}2}2} moieties bridging two Ag(I) centers.
