摘要

Four ternary solid complexes were synthesized with sodium diethyldithiocarbamate (NaEt2dtc) (b), 1,10-phenanthroline (o-phen) (c) and hydrated lanthanide chlorides in absolute ethanol by an improved reported method. The complexes were identified as the general formula of RE(Et2dtc)3(phen) (RE=La, Pr, Nd, Sm) by chemical and elemental analyses. IR spectra of the complexes showed that the RE3+ was coordinated with sulfur atoms of NaEt2dtc and nitrogen atoms of o-phen. The constant-volume combustion energies of complexes, △cU,were determined by a precise rotating-bomb calorimeter at 298.15 K. The standard enthalpies of combustion,(△cH-m), and standard enthalpies of formation, (△fH-m), were calculated for these complexes, respectively.
