摘要：
A series of lanthanide(III) complexes of the type [LnL(2)Cl(2)]Cl, where Ln = La, Ce, Pr, Nd, Sm, Eu, Gd,Tb, Dy, Ho, Er, Tm, Yb, Lu, L = C20H24N2O2, a bis-Schiff base ligand derived from salicylaldehyde and 1,6-hexanediamine, have been synthesized and characterized by elemental analyses, molar electrical conductivities, infrared and electronic spectra, thermergravimetric analyses.-All the complexes were found to be 1: 1 electrolytes of the general empirical formula [LnL(2)Cl(2)]Cl. The Schiff base ligand behaves as tetradentate ligand having a N2O2 donor sets towards the metal cations. A probable coordination number ten has been assigned in these complexes.
