A MoIV anion, a neutral MoV complex, and a mixed-valence MoIII/MoIV cation are found within the same crystal of the title compound 1, which is prepared by the reaction of [(Cp*MoBr2)2] with bromine in benzene. The coexistence of three oxidation states of molybdenum within 1 and the formation of 1 is rationalized based on the particular redox behavior of the individual constituents of the redox system Cp*MoBr/Br2.
