(3-Carboxy-5-sulfonatobenzoato-κ2O1,O1′)bis[2-(2-pyridyl)-1H-benzimidazole-κ2N2,N3]zinc(II) monohydrate

Abstract

In the title compound, [Zn(C8H4O7S)(C12H9N3)2]·H2O, the ZnII atom has a distorted octa­hedral coordination geometry, defined by four N atoms from two 2-(2-pyrid­yl)-1H-benzimidazole ligands and two O atoms from a deprotonated carboxyl­ate group of the 3-carb­oxy-5-sulfonatobenzoate ligand. In the crystal structure, the complex mol­ecules are linked into a three-dimensional network by inter­molecular O—H⋯O and N—H⋯O hydrogen bonds, and π–π stacking inter­actions with centroid–centroid separations of 3.758 (2) and 3.597 (1) Å.
