Bis(2, 2'-bipyridine-kappa^2N, N'(oxalato-kappa^2O, O')cobalt(II) pentahydrate

The synthesis and crystal structure of the mononuclear title compound, oxalatobis(2, 2'-bipyridine)cobalt(II) pentahydrate, [Co(C_2O_4)(C_10H_8N_2)_2]&middot ; ; 5H_2O, is reported. The Co atom is six-coordinated by two O atoms of the bidentate oxalate group and four N atoms of the two bipyridine ligands. The neutral [Co(C_2O_4)(C_10H_8N_2)_2] entities are connected by π -π stacking interactions of the aromatic systems into a two-dimensional layer, interconnected through a ladder-like hydrogen-bonding pattern of solvate water molecules.
