Di-chlorido-bis-[2-(pyridin-2-yl-κ)-1-benzimidazole-κ ]nickel(II) monohydrate.

In the title complex, [NiCl(CHN)]·HO, a divalent nickel atom is coordinated by two 2-(pyridin-2-yl)-1-benzimidazole ligands in a slightly distorted octa-hedral environment defined by four N donors of two ,'-chelating ligands, along with two -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 (2011 ▸). . , 7097-7107].
