catena-Poly[[[bis­(4-pyridine­aldoxime-κN¹)zinc]-μ-benzene-1,4-dicarboxyl­ato-κ²O¹:O⁴] 4-pyridine­aldoxime monosolvate]

In the title compound, {[Zn(C₈H₄O₄)(C₆H₆N₂O)₂]·C₆H₆N₂O}_n, the Zn^II ion exhibits a tetra­hedral 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-pyridine­aldoxime mol­ecule is located; this mol­ecule is linked by O—H...O and O—H...N hydrogen bonds to the zigzag chain.
