摘　　要：Solid complexes,RE(Et_(2)dtc)_(3)(phen)(RE=La,Pr,Nd,Sm-Lu),were synthesized with sodium diethyldithiocarbamate(NaEt_(2)dtc3H_(2)O),1,10-phenanthroline(o-phen·H_(2)O)and hydrated lanthanide chlorides in absolute ethanol.The constant-volume combustion energies of complexes,Δ_(c)U,were determined by a precise rotating-bomb calorimeter at 298.15 K.The standard enthalpies of combustion,Δ_(c)H^(θ)_(m),and standard enthalpies of formation,Δ_(f)H^(θ)_(m),were calculated for these complexes,respectively.The experiment results showed the'tripartite effect'of rare earth.
