摘要：

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 octahedral environment by two N atoms from two nicotinamide ligands and two water molecules in the equatorial plane, and two N atoms from two thiocyanate anions in the axial positions, all acting as monodentate ligands. In the crystal, weak N-H center dot center dot center dot S hydrogen bonds between the amino groups and the thiocyanate anions form an R-4(2) (8) motif. The complex molecules are linked by O-H center dot center dot center dot O, O-H center dot center dot center dot S, and N-H center dot center dot center dot S hydrogen bonds into a three-dimensional supramolecular structure. Weak pi-pi interactions between the pyridine rings is also found [centroid-centroid distance = 3.8578 (14) angstrom].
