title: catena-Poly[bis(μ(3)-3-aminobenzoato-κN:O:O,O')bis(μ(2)-3-aminobenzoato-κO,O':O)dilead(II)].
abstract: 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 nitro-gen donor and one oxygen donor in the axial positions. Two mol-ecules 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 carboxyl-ate O atoms into a chain along the b axis. Classical inter-molecular N-H⋯O hydrogen bonding is observed in the structure. The supra-molecular structure is consolidated by π-π stacking inter-actions with centroid-centroid distances between benzene rings of 3.837 (8) Å.
