Abstract

The reaction of lead(II) nitrate and benzoic acid in aqueous solution yields the title polymer, [Pb(C7H5O2)2(H2O)]n. The asymmetric unit contains one PbII ion, two benzoate ligands and one water mol­ecule. 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 inter­action. The PbII atom has a distorted penta­gonal-bipyramidal geometry chelated by two carboxyl­ate O atoms. The Pb atoms are bridged through a coordinating water mol­ecule and two carboxyl­ate O atoms from another two benzoate ligands, giving an infinite three-dimensional supra­molecular structure. O—H⋯O hydrogen-bonding inter­actions involved the coordinating water and carboxyl­ate O atoms enhance the stability of the supra­molecular arrangement.
