Abstract top

In the title polymer, [Pb(C7H4ClO3)2(C12H8N2)]n, the Pb(II) ion displays a distorted pseudo-octahedral coordination geometry. The metal center is coordinated by six O atoms from four 5-chlorosalicylate ligands and two N atoms from a chelating phenanthroline ligand. The polymeric structure is built up from bridging carboxylate O atoms, forming chains along [100]. The crystal structure is stabilized by [pi]-[pi] interactions between the 1,10-phenanthroline and 5-chlorosalicylate ligands, the shortest centroid-centroid separation between neighbouring aromatic rings being 3.652 (1) Å.

Comment top

The Pb(II) ion in the asymmetric unit is pseudo-octahedrally coordinated (Fig. 1), with coordination to six O atoms from four 5-chlorosalicylate ligands, and two N atoms from a chelating phenanthroline (phen) ligand. Two related complexes, [Zn(C7H4ClO3)2(C12H8N2)(H2O)] and [Cd(C7H4ClO3)2(C12H8N2)2], were reported (Wen & Ying, 2007; Wen et al., 2008, respectively), both with 5-chlorosalicylate ions acting as monodentate ligands, while in the title polymer, 5-chlorosalicylate ions are bidentate ligands.

The Pb—O distances (Table 1) vary from 2.458 (3) to 2.887 (3) Å, which are close to those found in Pb2(PMIDA).1.5H2O [from 2.331 (9) to 2.876 (9) Å; H4PMIDA is N-(phosphonomethyl)iminodiacetic acid]. Each pair of adjacent Pb(II) ions is bridged by the O1 atom of 5-chlorosalicylate, which forms a SBU (secondary building units, Fig. 2) including two Pb polyhedron, six 5-chlorosalicylate and two phen. The Pb···Pb distance in the dimeric unit is 4.3587 (2) Å. The SBU is bridged by O5 atom of 5-chlorosalicylate, to give rise to a zigzag chain (Fig. 3). The excellent coordinating ability and large conjugated systems of phen and 5-chlorosalicylate allow to form π···π interactions. The chains are extended into the framework through π..π interactions between the ligands from adjacent chains.

Experimental top

The pH value of a mixture of Pb(NO3)2 (0.5 mmol), phen (0.5 mmol) and 5-chlorosalicylic acid (0.5 mmol) in 8 ml of distilled water and 16 ml of ethanol was adjusted between 5 and 6 by addition of sodium hydroxide. The resultant solution was refluxed for 6 h. After cooling, yellow crystals were formed over 2 days, at room temperature.

Refinement top

H atoms were placed geometrically with bond lengths fixed to 0.82 (OH) and 0.93 Å (CH). Isotropic displacement parameters for H atoms were calculated as Uiso(H) = 1.2Ueq(carrier C) and Uiso(H) = 1.5Ueq(carrier O).
