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). 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.
硝酸铅（II）与苯甲酸在水溶液中的反应生成了标题聚合物[Pb(C₇H₅O₂)₂(H₂O)]ₙ。不对称单元包含一个Pb（II）离子、两个苯甲酸酯配体和一个水分子。Pb - O键长在2.494（4）- 2.735（4）Å范围内。Pb⋯Pb距离为4.0683（4）Å，表明金属 - 金属相互作用不显著。Pb（II）原子具有由两个羧酸根O原子螯合的扭曲五角双锥几何构型。Pb原子通过一个配位水分子和来自另外两个苯甲酸酯配体的两个羧酸根O原子桥连，形成无限的三维超分子结构。涉及配位水和羧酸根O原子的O - H⋯O氢键相互作用增强了超分子排列的稳定性。
