In the title coordination polymer, Pb(C(7)H(5)O(2))(NO(3))(C(10)H(8)N(2)), the Pb(II) ion is eight-coordinated by two N atoms from one 2,2'-bipyridine ligand, two O atoms from one benzoate anion and four O atoms from three nitrate groups (one chelating, two bridging) in a distorted dodecahedral geometry. Adjacent Pb(II) ions are linked by bridging nitrate O atoms through the central Pb(2)O(2) and Pb(2)O(4)N(2) cores, resulting in an infinite chain structure along the b axis. The crystal structure is stabilized by π-π stacking inter-actions between 2,2'-bipyridine and benzoate ligands belonging to neighboring chains, with shortest centroid-centroid distances of 3.685 (8) and 3.564 (8) Å.
