catena-Poly[[[bis­(4-pyridine­aldoxime-κN (1))zinc]-μ-benzene-1,4-dicarboxyl­ato-κ(2) O (1):O (4)] 4-pyridine­aldoxime monosolvate]

In the title compound, {[Zn(C(8)H(4)O(4))(C(6)H(6)N(2)O)(2)]·C(6)H(6)N(2)O}(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.
