Abstract: In the title one-dimensional polymer, [Zn(C₉H₆O₅)(C₇H₆N₂)₂]_n, the Zn^II center exhibits a deformed tetrahedral coordination geometry defined by two N atoms from two benzimidazole molecules and two carboxyl O atoms from two different 4-carboxyphenoxyacetate groups. Each 4-carboxyphenoxyacetate ligand acts in a bis-monodentate mode to connect two adjacent Zn^II ions, forming a chain structure. Hydrogen bonds serve to connect the chains into a two-dimensional supramolecular network.
