چکیده
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 tetra-dentate 6,6'-sulfanediylbis(2,2'-bi-pyridine) ligand coordinates to the CoII cation in the equatorial positions, while two water mol-ecules occupy the axial positions, forming a compressed octa-hedral 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).

In the centrosymmetric title compound, [Co(C6H12N4O3)2](NO3)2·4H2O, the Co(II) ion, lying on an inversion center, is O,N,O'-chelated by two nitrilo-triacetamide mol-ecules, forming a distorted octa-hedral geometry. In the crystal, extensive O-H⋯O and N-H⋯O hydrogen bonds link the complex cations, nitrate anions and lattice water mol-ecules into a three-dimensional network.
