The title compound, [Mn2O2(C10H8N2)4](ClO4)3.2C6H5NO2.0.5H2O, retains a half water molecule and incorporates two nitrobenzene molecules in the structure when recrystallized from a mixture of nitrobenzene and nitromethane. The two manganese sites have differing geometries suggestive of oxidation states MnIII and MnIV. The supposed d4 configuration of MnIII implies a Jahn-Teller distortion, which is observed.
