Methylcyclopentadienyl-substituted tungsten(IV) sulfide cluster [(eta(5)-Cp')(3)W3S4](+) and its heterobimetallic derivative [(eta(5)-Cp')(3)W3S4Ni(PPh3)](+)
The aqueous cluster salt [(H2O)9WS(4)][pts](4). 9H(2)O (pts p-toluenesulfonate) was converted to the methyl-cyclopentadienyl (Cp ') substituted cluster [(eta (5)-Cp ')(3)W3S4][Pts] ([1] [pts]) from which the cubane-like cluster [(eta (5)-Cp ' )W3S4Ni(PPh3)][pts] ([2][pts]) was obtained by reaction with Ni(cod)(2) and PPh3. [2][pts] was characterized by X-ray crystal structure analysis.
