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(NO_3)_3·DB24C8·2H_2O和[Y(NO_3)_3]_4·(DB24C8)_3·8H_2O,并对冠醚及其配合物的某些性质进行了对比研究。
The solid complex of scandium nitrate and yttrium nitrate with DB24C8 was synthesized by anhydrous acetonitrile, and its composition was determined as Sc (NO_3) _3 · DB24C8 · 2H_2O and [Y (NO_3) _3] _4 · (DB24C8) _3 · 8H 2 O and some properties of crown ethers and their complexes were compared.
