In the coordination polymer, poly[[{mu-1-[(1H-benzimidazol-2-yl) methyl]-1H-imidazole-kappa N-2:N'}(mu-5-carboxybenzene-1,3-dicarboxylato-kappa O-2(1):O-3)zinc(II)] dimethylformamide monosolvate pentahydrate], {[Zn(C9H4O6)(C11H10N4)]center dot C3H7-NO center dot 5H(2)O}(n), the Zn-II ion is coordinated by two N atoms from two symmetry-related 1-[(1H-benzimidazol-2-yl) methyl]-1H-imidazole (bmi) ligands and two O atoms from two symmetry-related 5-carboxybenzene-1,3-dicarboxylate (Hbtc(2-)) ligands in a slightly distorted tetrahedral geometry. The Zn-II ions are bridged by Hbtc(2-) and bmi ligands, leading to a 4-connected two-dimensional network with the topological notation (4(4).6(2)). Adjacent layers are further connected by 12 kinds of hydrogen bonds and also by pi-pi interactions, resulting in a three-dimensional supramolecular architecture in the solid state.
