Bis[(1 H-benzimidazol-2-yl)methanol-κ2 N, O](nitrato-κ2 O, O′)zinc(II) nitrate monohydrate.

The title compound, [Zn(NO3)(C8H8N2O)2]NO3·H2O, consists of a tris-chelated zinc cation and a nitrate anion, along with an uncoordinated water mol­ecule. These inter­act through O—H⋯O and N—H⋯O hydrogen bonds, giving rise to a three-dimensional network structure. The ZnII ion has an octa­hedral coordination. [ABSTRACT FROM AUTHOR]
