Catena-Poly[[bis[bis(1H-benzimidazole-κN3)zinc(II)]-μ4-benzene-1,2,4,5-tetracarboxylato] monohydrate

Abstract

In the title compound, {[Zn2(C10H2O8)(C7H6N2)4]·H2O}n, the ZnII 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 π–π stacking involving the benzimidazole rings. A non-coordinated water mol­ecule completes the structure.
