ABSTRACT
The standard (p_ = 0.1 MPa) molar enthalpies of formation of the crystalline complexes of dibenzoylmethane (HDBM), thenoyltrifluoroacetone (HTTFA), monothiodibenzoylmethane (HDBMS), and monothiothenoyltrifluoroacetone (HTTFAS) of copper(II) were determined, at T = 298.15 K, by high precision solution-reaction calorimetry. The standard molar enthalpies of sublimation of the copper(II) b-diketonate complexes were measured by high-temperature Calvet microcalorimetry. From the standard molar enthalpies of formation of the complexes in the gaseous state, the mean molar dissociation enthalpies copper(II)-ligand, AeDmae(Cu-L), were derived.
