Abstract

The heterometallic cubane-type clusters [(Cp*Mo)3(μ3-S)4Au(PR3)][PF6][X] (Cp* = η5-C5Me5; 2a: R = Ph, X = BF4; 2b: R = Cy, X = PF6; 2c: R = tBu, X = PF6), [(Cp*Mo)3(μ3-S)4Ag(PPh3)][PF6][OTf] (3, OTf = OSO2CF3) and [(Cp*Mo)3(μ3-S)4CuI][PF6] (4) have been prepared by the reaction of [(Cp*Mo)3(μ2-S)3(μ3-S)][PF6] (1) with complexes [(R3P)Au][X], [(Ph3P)Ag][OTf] and CuI, respectively. These clusters have been spectroscopically and crystallographically characterized. In addition, the electrochemical properties of clusters 2a, 2b, 2c and 4 are also discussed.
