| Abstract: The new complex ［Pb(TLA)NO3］NO3(TLA=tris(2-(6-methylpyridyl)methyl)amine)has been synthesized and characterized. Its cyrstal structure has been determined by X-ray diffraction method. The crystal is monoclinic system, and P21/n space group. The crystal cell parameters are found to be a=10.234(2),b=15.347(3)，c=15.395(3)?，β=99.93(2)°，V=2382(2)?3，Z=4，DC=1.85 kg/m3. The structure was solved by directed methods and Fouries syntheses. Final refinement by full matrix least-squares methods carried out. Convergence resulted in final unweighted and weighted agreement factors of 0.043 and 0.054. The Pb(Ⅱ) ion lies in a distorted square-pyramid environment composed of three Npyridyl and Namine from TLA ligand and one oxygen atom from nitrate group. |
