In the title compound, [Pb2(C9H4O6)2(C19H12N4)2], the PbII atom is five-coordinated by two N atoms from a chelating 2-phenyl-1H-1,3,7,8-tetraazacyclopenta[l]phenanthrene (L) ligand and three O atoms from two Hbtc ligands (H3btc is benzene-1,3,5-tricarboxylic acid), resulting in a distorted PbN2O3 coordination. Two PbII atoms are bridged by the Hbtc ligands, forming a discrete centrosymmetric dinuclear complex. Intermolecular N—H⋯O and O—H⋯O hydrogen bonds and π–π interactions between the pyridine and imidazole rings, and between the pyridyl rings of the L ligands [centroid–centroid distances = 3.600 (6) and 3.732 (6) Å] lead to a three-dimensional supramolecular structure.

The L ligand was synthesized according to the literature method (Steck & Day, 1943). The title compound was synthesized under hydrothermal conditions. A mixture of L (0.060 g, 0.2 mmol), H3btc (0.042 g, 0.2 mmol), Pb(NO3)2 (0.066 g, 0.2 mmol) and water (10 ml) in a mole ratio of 1:1:1:5000 was placed in a 25 ml Teflon-lined autoclave and heated for 3 d at 433 K under autogenous pressure. Upon cooling and opening the bomb, yellow block-shaped crystals were obtained, washed with H2O and dried in air (yield: 65% based on Pb).
H atoms on C and N atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 and N—H = 0.86 Å and Uiso(H) = 1.2Ueq(C,N). H atom of the carboxyl group was located from a difference Fourier map and refined as riding, with O—H = 0.82 Å and Uiso(H) = 1.5Ueq(O).
The design and construction of supramolecular architectures have received considerable attention in recent years, mostly motivated by their intriguing structural features and potential applications in catalysis, magnetism, molecular adsorption, non-linear optics and molecular sensing (Che et al., 2008). 2-Phenyl-1H-1,3,7,8-tetraazacyclopenta[l]phenanthrene (L) as an important phenanthroline derivative possesses fruitful aromatic systems and is a good candidate for the construction of metal–organic supramolecular architectures (Liu et al., 2009). In this paper, we selected benzene-1,3,5-tricarboxylic acid (H3btc) as a linker and L as a secondary ligand, resulting in the title complex.
In the title compound, the PbII atom is surrounded by two N atoms from one L ligand and three O atoms from two Hbtc ligands (Fig. 1). The neighboring two PbII atoms are bridged by the two Hbtc ligands, forming a sixteen-membered ring with a long Pb···Pb distance of 8.3037 (5) Å. Adjacent dimers are further linked through intermolecular N—H···O and O—H···O hydrogen bonds and π–π interactions between the pyridyl and imidazole rings and between the pyridyl rings of the L ligands [centroid–centroid distances = 3.600 (6) and 3.732 (6) Å], leading to a three-dimensional supramolecular structure (Fig. 2).

The design and construction of supramolecular architectures have received considerable attention in recent years, mostly motivated by their intriguing structural features and potential applications in catalysis, magnetism, molecular adsorption, non-linear optics and molecular sensing (Che et al., 2008). 2-Phenyl-1H-1,3,7,8-tetraazacyclopenta[l]phenanthrene (L) as an important phenanthroline derivative possesses fruitful aromatic systems and is a good candidate for the construction of metal–organic supramolecular architectures (Liu et al., 2009). In this paper, we selected benzene-1,3,5-tricarboxylic acid (H3btc) as a linker and L as a secondary ligand, resulting in the title complex.
In the title compound, the PbII atom is surrounded by two N atoms from one L ligand and three O atoms from two Hbtc ligands (Fig. 1). The neighboring two PbII atoms are bridged by the two Hbtc ligands, forming a sixteen-membered ring with a long Pb···Pb distance of 8.3037 (5) Å. Adjacent dimers are further linked through intermolecular N—H···O and O—H···O hydrogen bonds and π–π interactions between the pyridyl and imidazole rings and between the pyridyl rings of the L ligands [centroid–centroid distances = 3.600 (6) and 3.732 (6) Å], leading to a three-dimensional supramolecular structure (Fig. 2).
