摘要: 以无水乙腈为反应介质,合成了硝酸钪及硝酸钇与DB24C8的固态配合物,确定其组成为Sc(NO3)3·DB24C8·2H2O和[Y(NO3)3]4·(DB24C8)3·8H2O,并对冠醚及其配合物的某些性质进行了对比研究。

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.
