چکیده
In the title complex, [Ni(NCS)2(C6H6N2O)2(H2O)2], the Ni(II) ion is located on an inversion center and is coordinated in a distorted octa-hedral environment by two N atoms from two nicotinamide ligands and two water mol-ecules in the equatorial plane, and two N atoms from two thio-cyanate anions in the axial positions, all acting as monodentate ligands. In the crystal, weak N-H⋯S hydrogen bonds between the amino groups and the thio-cyanate anions form an R 4 (2)(8) motif. The complex mol-ecules are linked by O-H⋯O, O-H⋯S, and N-H⋯S hydrogen bonds into a three-dimensional supra-molecular structure. Weak π-π inter-actions between the pyridine rings is also found [centroid-centroid distance = 3.8578 (14) Å].
