Poly[diaqua­[μ₆-4,4′-(1,4-phenyl­ene)bis­(2,6-dimethyl­pyridine-3,5-dicarboxyl­ato)]dilead(II)]

The asymmetric unit of the title Pb-based coordination polymer, [Pb₂(C₂₄H₁₆N₂O₈)(H₂O)₂]_n, consists of one Pb^II cation, half of a 4,4′-(1,4-phenyl­ene)bis­(2,6-dimethyl­pyridine-3,5-di­carb­oxyl­ate (L⁴⁻) ligand and one coordinating water mol­ecule. The centers of the benzene ring of the ligand and the four-membered Pb/O/Pb/O ring are located on centers of inversion. The Pb^II ion is coordinated in form of a distorted polyhedron by seven O atoms from four separate L⁴⁻ ligands and by one water O atom. The PbO₇ polyhedra share O atoms, forming infinite zigzag [PbO₄(H₂O)]_n chains along [100] that are bridged by L⁴⁻ ligands, forming a two-dimensional coordination network parallel to (001). O—H...O hydrogen bonds involving the water mol­ecule are observed.
