Catena-Poly[[aqua-(3-methyl-benzoato-κO,O')lead(II)]-μ-3-methyl-benzoato-κO:O,O':O'].

ABSTRACT: The reaction of lead(II) acetate and 3-methyl-benzoic acid (MBA) in aqueous solution yielded the title polymer, [Pb(C(8)H(7)O(2))(2)(H(2)O)](n). The asymmetric unit contains two Pb(II) atoms, four MBA ligands and two water mol-ecules. Each Pb(II) cation is hepta-coordinated and chelated by four carboxyl-ate O atoms from two MBA ligands. The Pb atoms are bridged through the carboxyl-ate O atoms from another two MBA ligands, leading to a central Pb(2)O(2) core. The Pb-O bond lengths are in the range 2.325 (3)-2.757 (4) Å. The intra- and inter-dimer Pb⋯Pb distances are 4.2942 (3) and 4.2283 (3) Å, respectively, indicating little direct metal-metal inter-action. The coordinating water mol-ecules and carboxyl-ate O atoms are involved in extensive O-H⋯O hydrogen-bonding inter-actions. The comple
