Catena-Poly[[Bis­(4-Methyl­Benzoato-Κ2 O:O′)Lead(Ii)]-Μ-Nicotinamide-Κ2 N 1:O]

Abstract

In the title compound, [Pb(C8H7O2)2(C6H6N2O)]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)°. 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 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.
