catena-Poly[[bis(4-methylbenzoato-κ2O:O′)lead(II)]-μ-nicotinamide-κ2N1: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.
