Abstract
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 octa-hedral 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 mol-ecule 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 inter-actions, links the complex mol-ecules and the water mol-ecules to form a supra-molecular 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].
