Abstract: The unit cell of the title compound, [Mn₂(C₂O₄)(C₁₀H₈N₂)₄](ClO₄)₂·C₁₀H₈N₂, consists of a binuclear cation, two perchlorate anions, and one solvent 2,2'-bipyridine (bpy) molecule. In the complex cation [Mn₂(C₂O₄)(C₁₀N₂H₈)₄]²⁺, two Mn^II atoms are bridged by a bis(bidentate) oxalate ligand, each Mn^II atom being further coordinated by two bpy ligands in a distorted octahedral geometry. The distance between the two six-coordinated metal atoms is 5.583 (1) Å. - stacking interactions [interplanar distances between bpy rings = 3.739 (1) Å] are essential to the supramolecular assembly. There are extensive interionic C-HO interactions between the cations and between the cation and anion. Three of the four perchlorate O atoms are disordered over two sets of sites with occupancy ratios of 0.852 (6):0.148 (6).
