In the title compound, [Pb(C(8)H(7)O(2))(2)(C(6)H(6)N(2)O)] (n) , the PbII ion is coordinated by two 4-methylbenzoate (PMB) and one nicotinamide (NA) ligands while symmetry-related NA ligands bridge adjacent PbII ions, forming polymeric chains along the c axis. The carboxylate groups in the two PMB ions are twisted away from the attached benzene ring by 22.9 (2) and 4.6 (2)degrees. The two benzene rings of the PMB ions are oriented at a dihedral angle of 83.7 (1)degrees. In a polymeric chain, the NA ligands are linked to PMB ions through intramolecular N-H...O hydrogen bonds. In the crystal structure, adjacent polymeric chains interact via N-H...O and C-H...O hydrogen bonds, forming a two-dimensional network parallel to the bc plane.
