摘要: 合成了通式为RE(NCS)3·5DMSO的7种稀土元素异硫氰酸盐与二甲基亚砜的固态配合物(RE=La,Ce,Pr,Nd,Sm,Eu,Gd)。运用本文设计的热化学循环,采用量热法,测定了上述7种配合物在298.15K时的标准生成焓,并计算了它们的晶格能。

Abstract: The preparation of seven solid complexes of rare earth isothiocyanates with dimethylsulfox-ide(DMSO) was reported. Their chemical formulae were proved to be RE(NCS)3·5DMSOwhere REis La, Ce, Pr, Nd, Sm, Eu, Gd. By means of the thermochemical method, the standard molar enthalpies of formation of these complexes were determined and their lattice energies were calculated.

Key words: Standard molar enthalpy of formation, Rare earth, Isothiocyanate, Dimethylsulfoxide
