| 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)3.5DMSO where RE is 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. |
