Abstract: The zinc atom in the title compound, {[Zn(C₁₀H₈O₆)(C₃H₄N₂)₂]·4H₂O}_n, shows tetrahedral coordination; this atom, which lies on a position of site symmetry 2, is covalently bonded to the carboxyl O atom of one arm of the phenylenedioxydiacetate unit and datively bonded to the imidazole heterocycle. The polymeric chains propagate along the shortest axis of the orthorhombic unit cell and are assembled into layers. The phenylenedicarboxylate moiety lies on an inversion center and two of the three independent uncoordinated water molecules lie on twofold axes.
