Syntheses and characterization of lead (II) complexes based on 8-hydroxyquinolin (8-HQuin), [Pb(8- Quin)(X)]; X= N3-, Cl-, Br -, I- and NO3-

Five lead (II) complexes with the ligand 8-hydroxyquinolin (8-HQuin) containing different counter- ions, [Pb(8-Quin)(X)], (8-Quin= 8-Hydroxyquinolate, X= N3-, Cl-, Br -, I- and NO3- ), have been synthesized and characterized by elemental analysis and FT-IR. Only compound [Pb(8-Quin)(NO3)] was structurally characterized by single-crystal X-ray diffraction. The single crystal X-ray analysis shows that this complex is a one-dimensional (1D) polymer and the coordination numbers in PbII ions in this complex are six and seven, and coordination sphere is hemidirected.
