摘要

In the coordination polymer, poly[[{/^-l-[(li/-benzimidazol-2-yl)methyl]-li/-imidazole-/c:2Af:Af/}(/^-5-carboxybenzene-l,3-dicarboxylato-/c:2O1:O3)zinc(II)] di-methylformamide monosolvate pentahydrate], {[Zn(C9H4O6)(CiiH10N4)]-C3H7-NO-5H2O}n, the ZnII 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 (Hbtc2~) ligands in a slightly distorted tetrahedral geometry. The ZnII ions are bridged by Hbtc2~ and bmi ligands, leading to a 4-connected two-dimensional network with the topological notation (44.62). Adjacent layers are further connected by 12 kinds of hydrogen bonds and also by it-it interactions, resulting in a three-dimensional supramolecular architecture in the solid state.
