Abstract: In the title complex, [Ni(NCS)2(C6H6N2O)2(H2O)2], the NiII 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-HS hydrogen bonds between the amino groups and the thiocyanate anions form an R42(8) motif. The complex molecules are linked by O-HO, O-HS, and N-HS hydrogen bonds into a three-dimensional supramolecular structure. Weak - interactions between the pyridine rings is also found [centroid-centroid distance = 3.8578 (14) Å].
