| 摘 要： | Solid complexes, RE(Et2dtc)3(phen) (RE=La, Pr, Nd, Sm-Lu), were synthesized with sodium diethyldithiocarbamate (NaEt2dtc3H2O),1,10-phenanthroline (o-phen·H2O) and hydrated lanthanide chlorides in absolute ethanol. 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,ΔcHmθ, and standard enthalpies of formation,ΔfHmθ, were calculated for these complexes, respectively. The experiment results showed the "tripartite effect" of rare earth.

| Abstract: | Solid complexes, RE(Et2dtc)3(phen) (RE=La, Pr, Nd, Sm-Lu), were synthesized hydrated lanthanide chlorides in absolute ethanol. 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, AcHmθ, and standard enthalpies of formation, AfHmθ, were calculated for these complexes, respectively. The experiment results showed the "tripartite effect"of rare earth. |
