在乙腈中,水合硝酸钪同冠醚18C6形成了无色固态络合物:Sc(NO)_3.18C6.3H_2O。实验证明,在很宽的盐、醚摩尔比范围内均生成该组成的络合物。通过元素分析,红外光谱、X-射线衍射、差热及热重分析研究了络合物的一些特性。考查了络合物在一些有机溶剂中的溶解性,测定了它在18±0.1℃时在乙腈中的溶解度。此外,还研究了水合硝酸钪在乙腈中同冠醚DB18C6、B15C5、3′-NO2B15C5以及B12C4的络合作用以及溶剂丙酮对Sc(NO_3_)3和冠醚18C6络合作用的影响。
In acetonitrile, scandium nitrate hydrate with crown ether 18C6 to form a colorless solid complex: Sc (NO) _3.18C6.3H_2O. Experiments show that, in a wide range of salt, ether molar ratio of the complex formed by the composition. Some of the properties of the complexes were investigated by elemental analysis, infrared spectroscopy, X-ray diffraction, differential thermal and thermogravimetric analysis. The solubility of the complex in some organic solvents was investigated and its solubility in acetonitrile was determined at 18 ± 0.1 ° C. In addition, the complexation of scandium nitrate with crown ethers DB18C6, B15C5, 3’-NO2B15C5 and B12C4 in acetonitrile and the effect of solvent acetone on the complexation of Sc (NO3) 3 and crown ether 18C6 were also studied.
