In the title coordination polymer, [Pb(C7H5O2)(NO3)(C10H8N2)]n, the PbII ion is eight-coordinated by two N atoms from one 2,2′-bipyridine ligand, two O atoms from one benzoate anion and four O atoms from three nitrate groups (one chelating, two bridging) in a distorted dodecahedral geometry. Adjacent PbII ions are linked by bridging nitrate O atoms through the central Pb2O2 and Pb2O4N2 cores, resulting in an infinite chain structure along the b axis. The crystal structure is stabilized by ππ stacking inter­actions between 2,2′-bipyridine and benzoate ligands belonging to neighboring chains, with shortest centroid–centroid distances of 3.685 (8) and 3.564 (8) Å.

Comment top

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 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). To our knowledge, carboxylate coordinates metal in various ways, for example, in the mode of monodentate, bidentate chelating, bidentate bridging or chelating-bridging. It is well known that the introduction of chelate ligands such as 2,2'-bipyridine are capable of passivating metal sites via the N donors of the organic groups and may induce new structural evolution (Hagrman et al., 2000; Li et al., 2002). Herein, we report the structure of the title polymer.

The asymmetric unit of the title compound, [Pb(C10H8N2)(C7H5O2)(NO3)], contains a PbII cation, one 2,2'-bipyridine ligand, one benzoate and one nitrate ligand, as illustrated in in Fig.1. The PbII atom is eight-coordinated by two N atoms from one 2,2'-bipyridine ligand, two O atoms from one benzoate anion and four O atoms from three chelating-bridging nitrate ligands in a distorted dodecahedron geometry. The O3 and O5 atoms of bridging nitrato ligands link the adjacent PbII ions through the central Pb2O2 and Pb2O4N2 cores, resulting in an infinite chain structure along the b axis (Fig.2). The excellent coordinating ability and large conjugated systems of 2,2'-bipyridine and benzoato ligands allow to form π..π interactions. The chains are extended into the framework through π..π stacking interactions between the ligands belonging to the neighboring chains, with the shortest centroid-centroid distance of 3.685 (8) and 3.564 (8)Å.

Experimental top

A mixture of Pb(NO3)2 (0.09 g, 0.27 mmol), benzoic acid (0.102 g, 0.84 mmol), 2,2'-bipyridine (0.065 g, 0.41 mmol) and distilled water (10 ml) was sealed in a 25 ml Teflon-lined stainless autoclave. The mixture was heated at 403 K for 6 days to give the colorless crystals suitable for X-ray diffraction analysis.

Experimental. Refinement Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. Geometry All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
