Synthesis and Characterization of Open-ring Complexes Formed in the Reaction of Lanthanides(III)with Salicyl-aldehyde Schiff base Containing Pyridine and Amide Bridge

摘要

Eleven new lanthanide(III)complexes have been prepared by the reaction of lanthanide chlorides and the salicylaldehyde Scbjff base ligand(L)in ethanol solution.They have been characterized by elemental analysis,molar conductivity data,IR,UV and H NMR.The measured results shows that lanthanide(III)is coordinated with the Schiff base by ratio of 1:1.The formula of the complexes is [LnLH_2O]Cl_3,where Ln=La,Nd,Sm,Eu,Gd,Dy,Ho,Er,Tm,Yb and Lu.
