Abstract

SUMMARY

SYNTHESIS AND STUDY ON THE COMPLEXES OF SOME RARE EARTHS (Pr, Nd, Eu, Gd) WITH DL-ALANINE

The complexes of some rare earths with DL-alanine were synthesized. These solid complexes have the general formula [Ln(Ala)3]Cl3.3H2O [Ln: Pr, Nd, Eu, Gd  and  Ala: CH3CH(NH2)COOH]. The structure of  the complexes have been recognised on the basic of elemental analysis, conductivity measurements, IR spectra and thermal analysis methods. It was found that the DL-alanine utilized amino nitrogen and carboxyl oxygen for bonding.
