title: Poly[μ-aqua-di-μ-benzoato-lead(II)].
abstract: The reaction of lead(II) nitrate and benzoic acid in aqueous solution yields the title polymer, [Pb(C(7)H(5)O(2))(2)(H(2)O)](n). The asymmetric unit contains one Pb(II) ion, two benzoate ligands and one water mol-ecule. The Pb-O bond distances are in the range 2.494 (4)-2.735 (4) Å. The Pb⋯Pb distance is 4.0683 (4) Å, indicating an insignificant metal-metal inter-action. The Pb(II) atom has a distorted penta-gonal-bipyramidal geometry chelated by two carboxyl-ate O atoms. The Pb atoms are bridged through a coordinating water mol-ecule and two carboxyl-ate O atoms from another two benzoate ligands, giving an infinite three-dimensional supra-molecular structure. O-H⋯O hydrogen-bonding inter-actions involved the coordinating water and carboxyl-ate O atoms enhance the stability of the supra-molecular arrangement.
