Di-aqua-bis-(nicotinamide-κN (1))bis-(thiocyanato-κS)cobalt(II)

Abstract

In the title compound, [Co(NCS)2(C6H6N2O)2(H2O)2], the Co(II) cation is located on an inversion centre and is coordinated by two thio-cyanate anions, two nicotinamide mol-ecules and two water mol-ecules in a distorted N2O2S2 octa-hedral geometry. The amide group is twisted by 31.30 (16)° with respect to the pyridine ring. In the crystal, mol-ecules are linked by O-H⋯O, O-H⋯S and N-H⋯S hydrogen bonds into a three-dimensional supra-molecular network. Weak π-π stacking is observed between parallel pyridine rings of adjacent mol-ecules, the centroid-centroid distance being 3.8270 (19) Å.
