Mixed μ-phosphido or μ-thiolato μ-halo-dimolybdenum(III) compounds [Mo2Cp2(μ-SMe)2(μ-X)(μ-Y)] (X = PPh2, Y = Cl; X = SCH3, Y = Br, I): Electrochemical and structural comparisons - The X-ray structure of [{Mo2Cp2Br(μ-O)(μ-SMe)2}2(μ-MoO4)]

Mixed μ-phosphido or μ-thiolato μ-halo-dimolybdenum(III) compounds [Mo2Cp2(μ-SMe)2(μ-X)(μ-Y)] (X = PPh2, Y = Cl (1); X = SCH3, Y = Br (3), I (4)) have been studied. The influence of the bridging groups on the structures and electrochemical behaviour of the complexes [Mo2Cp2(μ-SMe)2(μ-X)(μ-Y)] 1-4 has been investigated. The X-ray structure of the original Mo5 system [{Mo2Cp2Br(μ-O)(μ-SMe)2}2(μ-MoO4)] (5), is reported.
