Aquachloridobis[2-(1,3-thia­zol-4-yl-κN)-1H-benzimidazole-κN (3)]nickel(II) nitrate

In the title compound, [NiCl(C(10)H(7)N(3)S)(2)(H(2)O)]NO(3), the Ni(II) 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].
