In the crystal of the title polymeric compound, {[Pb(C7H5O3)2(C6H6N2O)]·H2O}n, the PbII ion is chelated by two carboxylate groups of 3-hydroxybenzoate (HB) anions, and coordinated by one isonicotinamide molecule; a carboxylate O atom and a hydroxy O atom from adjacent HB anions bridge the PbII ion to form polymeric chains along [100], in which the PbII ion is in an irregular seven-coordination geometry. The carboxylate groups of the HB ions are slightly twisted away from the attached benzene rings by 2.84 (15) and 4.8 (2)°. The planes of the two benzene rings of the HB ions are oriented with respect to each other at a dihedral angle of 84.41 (8)°. In the crystal, adjacent polymeric chains interact via O—H⋯O, N—H⋯O and weak C—H⋯O hydrogen bonds. The solvent water molecule links with the polymeric chains via O—H⋯O hydrogen bonding. π–π stacking between the benzene and pyridine rings and between the benzene rings [centroid–centroid distances = 3.731 (2) and 3.353 (2) Å] are present in the crystal.
