Synthesis and Characterization of Schiff Base Crown Ether Complexes with Rare Earth
Abstract:
A new Schiff base crown ether 2,5,14,17-tetraoxa-11,20-diazatricyclo[20,2,2,26,9]-octacosa-1(24),6,8,10,21,23,25,27-octene was prepared by condensation of ethylenedioxybis (4-formylbenzene) with 2,2'-(ethylenedioxy)bis(ethylamine) in anhydrous acetonitrile. It's rare earth(Nd,Gd,Y) nitrate complexes were prepared and characterized by elemental analysis, TG-DTA, electric conductivity measurements and IR spectroscopy. The three complexes have the same molecular structure, and the nitrogen atoms in Schiff base do not take part in coordination.
