【摘要】 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）₃.18C6.3H₂O。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。更多还原

【Abstract】 The complex Sc（NO₃）₃·18C6· 3H₂O in solid state was prepared using CH₃CN or CH₃COCH₃ as solvent The complex was characterized By elemental analysis, infrared spectra, themogravimetric and differential thermal analysis as well as X-ray diffraction. The solubility of the complex in several organic solvents was studed. Besides, the complexation of trihydrated scandium nitrate with some crown ethers（dibenzo-18-crown-6, benzo-15-crown-5. 3’-NO₂-benzo-15-crown-5 and benzo-12-corwn-4） has been investigated.更多还原
