Treatment of [Cp*Mo(SBut)3] (1; Cp* = 
5-C5Me5) with [Fc][PF6] (Fc = ferrocene) afforded thecationic sulfido-bridged dinuclear complex [(Cp*MoS)(
2-S)2(Cp*Mo)(S2But)][PF6] (2) and the cationic incomplete cubane-type complex [(Cp*Mo)3(2-S)3(3-S)][PF6](3) in a ratio of ca. 1:4. The dinuclear complex 2 reactedwith [NiCl2(PPh3)2] and [Ni(cod)2] (cod = 1,5-cyclooctadiene) to give the heterobimetallic cluster [(Cp*Mo)2{Ni(PPh3)}2(2-S)2(3-S)3][PF6] (4) with an unprecedentedMo2Ni2S5 core and the edge-linked quadruple cubane-type cluster [(Cp*Mo)2Ni2(3-S)2(4-S)2]4[PF6]4 (5) withfour Mo2Ni2S4 cores, respectively. On the other hand, theincomplete cubane-type cluster 3 serves as a good precursor to the heterobimetallic cubane-type clusters [(Cp*Mo)3(3-S)4M'L][PF6] (M' = Ru, Ni, and Pd).
