Abstract: In the title compound, {[Zn(C₁₀H₈N₂)(H₂O)₄](C₈H₄O₄)}_n, the Zn^II atoms, lying on a twofold rotation axis, are bridged by 4,4'-bipyridine ligands, resulting in a linear chain along the b axis. In the chain, the Zn^II atom adopts a slightly distorted octahedral coordination geometry involving four water molecules at the equatorial positions. The noncoordinated benzene-1,4-dicarboxylate anion, which is also located on a twofold rotation axis, bridges adjacent chains through O-HO hydrogen bonds, forming a three-dimensional supramolecular network.
