In the title compound, [NiCl(C10H7N3S)2(H2O)]NO3, the NiII ion is coordinated by four N atoms from two chelating 2-(1,3-thiazol-4-yl)-1H-benzimidazole ligands, one Cl atom and one water molecule in a distorted octahedral geometry. In the crystal, O—H⋯O, N—H⋯O and N—H⋯Cl hydrogen bonds link the complex cations and nitrate anions into a three-dimensional network. π–π interactions between the thiazole and imidazole rings and between the thiazole and benzene rings are observed [centroid–centroid distances = 3.592 (3) and 3.735 (3) Å].
