Abstract: In the title compound, {[Zn(C8H4O4)(C6H6N2O)2]·C6H6N2O}n, the ZnII ion exhibits a tetrahedral coordination environment defined by two benzene-1,4-dicarboxylate dianions and two 4-pyridinealdoxime ligands. The dianions bridge the ZnII ions, giving a zigzag chain along the b axis. Adjacent chains are connected by O-H...O hydrogen bonds, forming a cavity in which an uncoordinating 4-pyridinealdoxime molecule is located; this molecule is linked by O-H...O and O-H...N hydrogen bonds to the zigzag chain.
