Abstract: In the title one-dimensional polymer, {[Zn(3-CPOA)(C₃H₄N₂)₂]·3H₂O}_n (3-CPOA^2- is the 3-carboxylatophenoxyacetate dianion, C₉H₆O₅), the Zn atom shows tetrahedral coordination, as it is linked to two N atoms from two imidazole molecules and two carboxylate O atoms from two different 3-CPOA^2- groups. Adjacent Zn atoms are linked by 3-CPOA^2- ligands into a helical chain. The chains are linked into a three-dimensional network by hydrogen bonds.
