Z. An and R.-S. Wang

Abstract: In the title compound, {[Zn₂(C₁₀H₂O₈)(C₇H₆N₂)₄]·H₂O}_n, the Zn^II atom has a distorted tetrahedral geometry, defined by two N atoms from two benzimidazole ligands and two O atoms from two benzene-1,2,4,5-tetracarboxylate (btc) tetra-anions. The complete btc anion is generated by inversion symmetry. The polymeric structure exhibits one-dimensional double chains running along the [100] direction, which further extend into a three-dimensional supramolecular network by way of - stacking involving the benzimidazole rings. A non-coordinated water molecule completes the structure.
