catena-Poly[[[bis-(4-pyridine-aldoxime-κN (1))zinc]-μ-benzene-1,4-dicarboxyl-ato-κ(2) O (1):O (4)] 4-pyridine-aldoxime monosolvate].

In the title compound, {[Zn(C8H4O4)(C6H6N2O)2]·C6H6N2O} n , the Zn(II) ion exhibits a tetra-hedral coordination environment defined by two benzene-1,4-dicarboxylate dianions and two 4-pyridinealdoxime ligands. The dianions bridge the Zn(II) 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-pyridine-aldoxime mol-ecule is located; this mol-ecule is linked by O-H⋯O and O-H⋯N hydrogen bonds to the zigzag chain.
