On the thermal stability of europium- and gadolinium glycinates

Thermal stability of gadolinium and europium glycinates of the 1:1, 1:2, 1:3 composition, prepared in the solid state for the first time is studied. Thermal decomposition of complexes follows the dehydration process. On the basis of derivatography data an assumption is made about a double nature of water bond in REE complexes with glycine Dehydration is accompanied by the alte ations in the crystal lattice of Cd complexes with glycinate./ Thermal stability of europium glycinates is higher than that/ of gadolinium and depends upon the stoichiometric composition/ of complexes. On the basis of IR spectra data the assumption/ is accompanied by the alterations in the crystal lattice of Cd complexes with glycinate. Thermal stability of europium glycinates is higher than that of gadolinium and depends upon the stoichiometric composition of complexes. On the basis of IR spectra data the assumption is made about the possible glycine coordination with metals
