Abstract
The three-dimensional polymeric title compound, {[Zn(C9H4N2O4)]·H2O}n, contains one crystallographically independent ZnII atom, one fully deprotonated 1H-benzimidazole-5,6-dicarboxylate (bdc) ligand and one uncoordinated water molecule. The ZnII atom is four-coordinated by three O atoms and one N atom from the bdc ligands, giving a distorted tetrahedral coordination geometry. The uncoordinated water molecule is bound to the main structure through a strong bdc–water N—H⋯O hydrogen bond, and two much weaker water–bdc O—H⋯O interactions.
