Abstract

The CoII atom in the title compound, [Co(C12H8N5)2(H2O)4]·2H2O, lies on a center of inversion and is bonded to two N-heterocycles and to four water mol­ecules in a slightly distorted octahedral coordination. The coordinated and lattice water mol­ecules inter­act with the N-heterocycles through O—H⋯N hydrogen bonds, generating a three-dimensional supra­molecular architecture.
