چکیده
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-phenyl-ene)bis-(2,6-dimethyl-pyridine-3,5-di-carb-oxyl-ate (L (4-)) ligand and one coordinating water mol-ecule. 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 L (4-) 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 L (4-) ligands, forming a two-dimensional coordination network parallel to (001). O-H⋯O hydrogen bonds involving the water mol-ecule are observed.
