HETERONUCLEAR AMINOPOLYCARBOXYLATES OF LANTHANIDES (III) AND BISMUTH (III)

Abstract

Comparison of two methods of synthesis of heteronuclear complexes of Bi(III) on the base of aminopolycarboxylic acids of different structure with neodymium and terbium was made. Identification of the complexes was made by elemental analysis, IR- and PMR-spectroscopy. Theoretical analysis of geometry of complexes was performed using molecular mechanics method. 4f-Luminescence of Tb(III) was observed in all heteronuclear complexes.
