چکیده
In the crystal of the title polymeric compound, {[Pb(C(7)H(5)O(3))(2)(C(6)H(6)N(2)O)]·H(2)O}(n), the Pb(II) ion is chelated by two carboxyl-ate groups of 3-hy-droxy-benzoate (HB) anions, and coordinated by one isonicotinamide mol-ecule; a carboxyl-ate O atom and a hy-droxy O atom from adjacent HB anions bridge the Pb(II) ion to form polymeric chains along [100], in which the Pb(II) ion is in an irregular seven-coordination geometry. The carboxyl-ate 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 inter-act via O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds. The solvent water mol-ecule 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.
