Di­chlorido­bis­[2-(pyridin-2-yl-κN)-1H-benzimidazole-κN (3)]nickel(II) monohydrate

In the title complex, [NiCl(2)(C(12)H(9)N(3))(2)]·H(2)O, a divalent nickel atom is coordinated by two 2-(pyridin-2-yl)-1H-benzimidazole ligands in a slightly distorted octa­hedral environment defined by four N donors of two N,N′-chelating ligands, along with two cis-oriented anionic chloride donors. The title complex crystallized with a water mol­ecule disordered over two positions. In the crystal, a combination of O—H⋯Cl, O—H.·O and N—H⋯Cl hydrogen bonds, together with C—H⋯O, C—H⋯Cl and C—H⋯π inter­actions, links the complex mol­ecules and the water mol­ecules to form a supra­molecular three-dimensional framework. The title complex is isostructural with the cobalt(II) dichloride complex reported previously [Das et al. (2011 ▸). Org. Biomol. Chem. 9, 7097–7107]. [Image: see text]
