μ-Oxalato-bis­[bis­(2,2′-bipyridine)­manganese(II)] bis(perchlorate) 2,2′-bipyridine solvate

The unit cell of the title compound, [Mn(2)(C(2)O(4))(C(10)H(8)N(2))(4)](ClO(4))(2)·C(10)H(8)N(2), consists of a binuclear cation, two perchlor­ate anions, and one solvent 2,2′-bipyridine (bpy) mol­ecule. In the complex cation [Mn(2)(C(2)O(4))(C(10)N(2)H(8))(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. π–π stacking inter­actions [inter­planar distances between bpy rings = 3.739 (1) Å] are essential to the supramolecular assembly. There are extensive inter­ionic C—H⋯O 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).
