Methylcyclopentadienyl-Substituted Tungsten(IV) Sulfido Cluster [(η⁵-Cp‘)₃W₃S₄]⁺ and Its Heterobimetallic Derivative [(η⁵-Cp‘)₃W₃S₄Ni(PPh₃)]⁺

The aqueous cluster salt [(H2O)9W3S4][pts]4·9H2O (pts = p-toluenesulfonate) was converted to the methylcyclopentadienyl (Cp‘) substituted cluster [(η5-Cp‘)3W3S4][pts] ([1][pts]) from which the cubane-like cluster [(η5-Cp‘)3W3S4Ni(PPh3)][pts] ([2][pts]) was obtained by reaction with Ni(cod)2 and PPh3. [2][pts] was characterized by X-ray crystal structure analysis.
