The asymmetric unit of the title salt, [Co(C20H14N4S)(H2O)2](NO3)2, comprises a [Co(C20H14N4S)(H2O)2]2+ cation and two NO3− anions. In the complex, [Co(C20H14N4S)(H2O)2]2+ cation, the tetradentate 6,6′-sulfanediylbis(2,2′-bipyridine) ligand coordinates to the CoII cation in the equatorial positions, while two water molecules occupy the axial positions, forming a compressed octahedral CoN4O2 coordination sphere. The NO3− anions are linked to the [Co(C20H14N4S)(H2O)2]2+ cations via O—H...O hydrogen bonds, yielding a layered arrangement parallel to (001).
