| 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, ΔcU, were determined by a precise rotating-bomb calorimeter at 298.15 K. The standard enthalpies of combustion, ΔcHm?, and standard enthalpies of formation, ΔfHm?, were calculated for these complexes, respectively.

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, , and standard enthalpies of formation, , were calculated for these complexes, respectively. |
