catena-Poly[bis(μ(3)-3-aminobenzoato-κ(4) N:O:O,O′)bis(μ(2)-3-aminobenzoato-κ(3) O,O′:O)dilead(II)]

The Pb(II )atom in the title compound, {[Pb(2)(C(7)H(6)NO(2))(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 μ(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 π–π stacking inter­actions with centroid–centroid distances between benzene rings of 3.837 (8) Å.
