The reaction of lead(II) acetate and 3-methylbenzoic acid (MBA) in aqueous solution yielded the title polymer, [Pb(C8H7O2)2(H2O)]n. The contains two PbII atoms, four MBA ligands and two water molecules. Each PbII cation is heptacoordinated and chelated by four carboxylate O atoms from two MBA ligands. The Pb atoms are bridged through the carboxylate O atoms from another two MBA ligands, leading to a central Pb2O2 core. The Pb—O bond lengths are in the range 2.325 (3)–2.757 (4) Å. The intra- and interdimer Pb⋯Pb distances are 4.2942 (3) and 4.2283 (3) Å, respectively, indicating little direct metal–metal interaction. The coordinating water molecules and carboxylate O atoms are involved in extensive O—H⋯O hydrogen-bonding interactions. The complex has an extended ladder-like chain structure and the chains are assembled by hydrogen bonds and π–π interactions [centroid–centroid distance = 3.6246 (3) Å] into a three-dimensional supramolecular structure.

A mixture of Pb(CH3COO)2 3H2O (0.1992 g, 0.52 mmol), MBA (0.1139 g, 0.84 mmol), melamine (0.0255 g, 0.20 mmol) and distilled water (10 ml) was sealed in a 25 ml Teflon-lined stainless autoclave (Shi et al. 2007). The mixture was heated at 373 K for 5 days to give colorless crystals suitable for X-ray diffraction analysis.
All H atoms bounded to C atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H distances in the range of 0.93–0.96 Å. The positions of the water H atoms were found from a difference Fourier map and refined with distance restraints O—H = 0.82 Å, Uiso(H) = 1.2Ueq(O).

Interest in porous metal-organic frameworks (MOFs) has been driven by the prospect of generating a wide range of materials with useful properties for applications such as ion-exchange, nonlinear optics and catalysis (Hamilton et al., 2004; Meng et al., 2003; Fan et al. 2006). On the other hand, lead(II) compounds have been increasingly studied (Shi et al. 2007) owing to their possible applications in different fields, especially in environmental protection due to the toxicity of lead and in biological systems for its diverse interactions with biological molecules. As an important family of multidentate O-donor ligands, aromatic carboxylate ligands have been extensively employed in the preparation of metal-organic complexes because of their potential properties and intriguing structural topologies (Wang et al., 2006; Masaoka et al. 2001). Herein, we report the structure of the title complex.
The asymmetric unit of the title complex, [Pb2(C8H7O2)4(H2O)2]n, contains two PbII cation, four MBA ligands and two coordinating water molecule, as illustrated in Fig. 1. The two Pb atoms are connected via two bridging O atoms belonging to two MBA ligands, resulting the central Pb2O2 core tetratomic ring. The Pb—O bond lengths are in the range of 2.325 (3) to 2.757 (4) Å (Table 1). The average distance of two Pb atoms is 4.2942 Å, which leads to the weak metal-metal interactions. This coordination polymer structure presents extended ladder-like chain along the a axis direction. The coordinating water molecules and carboxylate O atoms are involved in extensive O—H···O hydrogen-bonding interactions (Table 2). These chains are assembled by H-bonds and π-π interactions to three-dimensional supramolecular structure.
