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, , and standard enthalpies of formation, , were calculated for these complexes, respectively.
Four ternary solid complexes were synthesized with sodium diethyldithiocarbamate (NaEt(2)dtc) (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(Et(2)dtc)(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 NaEt(2)dtc and nitrogen atoms of o-phen. The constant-volume combustion energies of complexes, Delta(c)U, were determined by a precise rotating-bomb calorimeter at 298.15 K. The standard enthalpies of combustion, Delta(c)H(m)(circle minus) and standard enthalpies of formation, Delta(f)H(m)(circle minus) were calculated for these complexes, respectively.
