The reaction of lead acetate, benzoic acid and 2,2′-bipyridine (bipy) in aqueous solution yielded the title complex, [Pb(C7H5O2)2(C10H8N2)]·C7H6O2. The contains two independent complex molecules as well as two independent benzoic acid solvent molecules, one of which is disordered over two positions with almost equal occupancies [0.504 (5) and 0.496 (5)]. The two complex molecules have similar configurations with the hexacoordinated environment of the PbII atom formed by four carboxylate O atoms of two chelate benzoate ligands and two N atoms of the bipy ligand. The Pb—O bonds involving one of the benzoate ligands are almost coplanar with Pb—N bonds to the bipy ligand [dihedral angles of 12.67 (11) and 14.73 (11)°] ; if the second benzoate ligand is treated as one coordination site, the overall coordination may be represented as a distorted pseudo-square pyramid. Weak intermolecular Pb⋯O interactions [3.046 (3) and 3.359 (3) Å] link each of the complex molecules into two symmetry-independent centrosymmetric dimers. Hydrogen bonds involving the carboxyl H atoms of solvent benzoic acid molecules and metal-coordinated carboxylate O atoms link complex molecules and benzoic acid solvent molecules into insular aggregates.

A mixture of Pb(CH3COO)2.3H2O (0.199 g, 0.52 mmol), benzoic acid (0.102 g, 0.84 mmol), 2,2'-bipyridine (0.033 g, 0.21 mmol) and distilled water (10 ml) was sealed in a 25 ml Teflon-lined stainless autoclave. The mixture was heated at 393 K for 6 days to give the colorless crystals suitable for X-ray diffraction analysis.
All H atoms bound to C atoms were placed in calculated positions and treated in a riding-model approximation, with C —H = 0.93 Å and Uiso (H) = 1.2 Ueq(C). The positions of carboxylic H atoms were located in the difference Fourier maps and included in the
in riding motion approximation with idealized distance of O—H = 0.85 Å and Uiso (H) = 1.2 Ueq(O). One of the the benzoic acid molecules [C56—C57—C58—C59—C60—C61—C62—O11—O12—H12] showed high thermal parameters and was subsequently represented as disordered over two sites, with refined occupancies of 0.496 (5) and 0.504 (5). The displacement parameters for the corresponding non-hydrogen atoms in the disordered phenyl rings were set equal (six EADP instructions; see, Sheldrick, 2008). The highest residual peak of 1.17 e Å-3 is located at the distance of 0.89 Å from Pb1; the deepest hole -1.13 e Å-3 is at 0.65 Å from the same atom.Complexes containing Pb(II) ion have recently attracted considerable interest not only because of the variety of their architectures, but also because of their potential applications, especially in environmental protection and in systems with different biological properties (Fan & Zhu, 2006; Hamilton et al., 2004; Alvarado et al., 2005). As an important family of bidentate O-donor ligands, aromatic carboxylates have been extensively employed in the preparation of metal complexes of various structural topologies (Wang et al., 2006; Masaoka et al., 2001).
The
of the crystal of the title complex, [Pb(C7H5O2)2(C10H8N2)].(C7H6O2), contains two molecules of complex, as well as two independent benzoic solvate molecules (Fig.1), one of which is disordered over two positions with almost equal occupancies. Each PbII atom is hexacoordinated and chelated by four carboxylate O atoms from two benzoic acid and two N atoms from 2,2'-bipyridine ligand. In both complex molecules the O atoms of one of the carboxylate ligands (O3 and O4 in the first molecule; O7 and O8 in the second molecule) are almost coplanar with the N atoms of the bipy-ligand (N1 and N2 in the first and N3 and N4 in the second molecule). Therefore, if we consider, that the second carboxylate ligand occupies just one coordination site, then coordination environments of Pb1 and Pb2 atoms may be described as pseudo-square-pyramidal.The weak intermolecular interactions Pb1···O2i [3.359 (3) Å, i -x, 1 - y, 2 - z] and Pb2···O7ii [3.046 (3) Å, ii 1 - x, 1 - y,1 - z] link the molecules of complex into centrosymmetric dimers (Fig.2). The H-bonds involving carboxylic H atoms of solvate benzoic acid molecules and metal coordinated carboxylate O atoms (Table 1), link molecules of the complex and benzoic acid solvates into insular aggregates.

Complexes containing Pb(II) ion have recently attracted considerable interest not only because of the variety of their architectures, but also because of their potential applications, especially in environmental protection and in systems with different biological properties (Fan & Zhu, 2006; Hamilton et al., 2004; Alvarado et al., 2005). As an important family of bidentate O-donor ligands, aromatic carboxylates have been extensively employed in the preparation of metal complexes of various structural topologies (Wang et al., 2006; Masaoka et al., 2001).
The asymmetric unit of the crystal of the title complex, [Pb(C7H5O2)2(C10H8N2)].(C7H6O2), contains two molecules of complex, as well as two independent benzoic solvate molecules (Fig.1), one of which is disordered over two positions with almost equal occupancies. Each PbII atom is hexacoordinated and chelated by four carboxylate O atoms from two benzoic acid and two N atoms from 2,2'-bipyridine ligand. In both complex molecules the O atoms of one of the carboxylate ligands (O3 and O4 in the first molecule; O7 and O8 in the second molecule) are almost coplanar with the N atoms of the bipy-ligand (N1 and N2 in the first and N3 and N4 in the second molecule). Therefore, if we consider, that the second carboxylate ligand occupies just one coordination site, then coordination environments of Pb1 and Pb2 atoms may be described as pseudo-square-pyramidal.
The weak intermolecular interactions Pb1···O2i [3.359 (3) Å, i -x, 1 - y, 2 - z] and Pb2···O7ii [3.046 (3) Å, ii 1 - x, 1 - y,1 - z] link the molecules of complex into centrosymmetric dimers (Fig.2). The H-bonds involving carboxylic H atoms of solvate benzoic acid molecules and metal coordinated carboxylate O atoms (Table 1), link molecules of the complex and benzoic acid solvates into insular aggregates.
