Abstract: In the title polymeric complex, {[Zn(C₈H₄O₄)(C₃H₄N₂)₂]·3H₂O}_n, the Zn^II atom is coordinated by two terephthalate dianions and two imidazole ligands in a distorted tetrahedral geometry. The terephthalate dianions are located on inversion centres and bridge neighbouring Zn^II atoms to form zigzag polymeric complex chains. The interplanar distance of 3.212 (17) Å between parallel imidazole rings of adjacent polymeric chains suggests the existence of - stacking.
