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