Abstract

The title compound, (C15H13N3)4[ReBr6][ReBr4O(H2O)]2Br4·2H2O, is a mixed‐valence molecular salt containing rhenium(IV) (as centrosymmetric [ReBr6]2− anions) and rhenium(V) (as trans‐[ReO(H2O)Br4] oxidoanions). The Re—O and Re—Br distances are consistent with the different oxidation states of Re in the anions. A complex hydrogen‐bonding network helps to establish the crystal packing.
