Abstract: The solid complexes of scandium and yttrium nitrates with dibenzo-24-crown-8(DB24C8), having the compositions Sc(NO3)3·DB24C8· 2H2O and [Y(NO3)3]4·(DB24C8)3·8H2O, were synthesized in acetonitrile medium and characterized by elemental analyses, JRand UVspectra, thermogravimetric (TG) and differential thermal analyses and X-ray powder diffraction.
