Özet

In the crystal structure of the polymeric title compound, {[Pb(C9H9O2)(2)(C6H6N2O)]center dot H2O}(n), the six-coordinate Pb-II ion is chelated by two 4-ethylbenzoate (PEB) anions and is bridged by two nicotinamide (NA) ligands, forming a polymeric chain running along the b axis. The carboxylate groups of the PEB ions are twisted away from the attached benzene rings by 4.0 (6) and 13.3 (5)degrees. The two benzene rings of the PEB ions bonded to the same metal ion are oriented at a dihedral angle of 87.4 (3) . In the polymeric chain, the N-A ligand is linked to one of the carboxylate groups via N-H center dot center dot center dot O hydrogen bonding. In the crystal, adjacent polymeric chains interact via N-H center dot center dot center dot O and weak C-H center dot center dot center dot O hydrogen bonds; and the lattice water molecule links with the polymeric chains via N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonding. pi-pi stacking between the benzene and the pyridine rings [centroid-centroid distance = 3.805 (5) angstrom] and weak C-H center dot center dot center dot center dot pi interactions are also observed in the crystal structure.
