A series of dinuclear homo- and heterometallic complexes with two or three bridging sulfido ligands derived from the tungsten tris(sulfido) complex [Et4N][(Me(2)Tp)WS3] (Me(2)Tp = hydridotris(3,5-dimethylpyrazol-1-yl)borate)
The generation of heterobimetallic complexes with two or three bridging sulfido ligands from mononuclear tris(sulfido) complex of tungsten [Et4N][(Me(2)Tp)WS3] (1; Me(2)Tp = hydridotris(3,5-dimethylpyrazol-1-yl) borate) and organometallic precursors is reported. Treatment of 1 with stoichiometric amounts of metal complexes such as [M(PPh3)(4)] (M = Pt, Pd), [(PtMe3)(4)(mu(3)-l)(4)] [M(cod)(PPh3)(2)][PF6] (M = Ir, Rh; cod = 1,5-cyclooctadiene), [Rh(cod)(dppe)][PF6] (dppe = Ph2PCH2CH2PPh2), [Cp*Ir(MeCN)(3)][PF6](2) (CP* = eta(5)-C5Me5 [Cp*Ru(MeCN)(3)][PF6], and [M(CO)(3)-(MeCN)(3)] (M = Mo, W) in MeCN or MeCN-THF at room temperature afforded either the doubly bridged complexes [Et4N][(Me(2)Tp)W(=S)W(mu-S)(2)M(PPh3)] (M = Pt (3), Pd (4)), [(Me(2)Tp)W(=S) (mu-S)(2)M(cod)] (M = Ir, Rh (7)), [(Me(2)Tp)W(=S)(mu-S)(2)Rh(dppe)], [(Me(2)Tp)W(=S)(mu-S)(2)RuCp*] (10), and [Et4N][(Me(2)Tp)W(=S)(mu-S)(2)W(CO)(3)] (12) or the triply bridged complexes including [(Me(2)Tp)W(U-S)(3)PtMe3] (5), [(Me(2)Tp)W(U-S)(3)IrCp*][PF6] (9), and [Et4N][(Me(2)Tp)W(mu-S)(3)Mo(CO)(3)] (11), depending on the nature of the incorporated metal fragment. The X-ray analyses have been undertaken to clarify the detailed structures of 3-5, 7, and 9-12.
