The title compound, [Rez(OH)(C12H12N2)(2)(CO)(6)][ReO4].-0.5C(3)H(6)O, is the first crystal structure reported for a hydroxo-bridged binuclear rhenium complex containing bipyridine or substituted bipyridine ligands. The cation has distorted octahedral coordination about both rhenium centers, resulting from geometric constraints imposed by the chelating 4,4'-dimethyl-2,2'-bipyridine ligands, which are involved in an intermolecular pi-pi stacking interaction. The distance between the rhenium atoms is 4.0185 (3) Angstrom, with no metal-metal bond. The H atom of the bridging hydroxo ligand was directly located in the crystallographic analysis, and is hydrogen-bonded to the perrhenate. The acetone solvent molecule is disordered.
