The PbII atom in the title compound, {[Pb2(C7H6NO2)4]}n, is chelated by two 3-aminobenzoato ligands in a distorted pentagonal-bipyramidal coordination geometry with five oxygen donors in the equatorial positions, one nitrogen donor and one oxygen donor in the axial positions. Two molecules are linked through a centre of inversion, forming a dinuclear entity. These entities are linked in a [mu]3-bridging mode through the amino N atom and two carboxylate O atoms into a chain along the b axis. Classical intermolecular N-H...O hydrogen bonding is observed in the structure. The supramolecular structure is consolidated by [pi]-[pi] stacking interactions with centroid-centroid distances between benzene rings of 3.837 (8) Å.
