Abstract (EN): The standard (p(0)=0.1 MPa) molar enthalpies of formation, at T=298.15 K, in the gaseous phase, for three tetradentate Schiff bases involving a N2O2 set, N,N'-bis(salicylaldehydo)cyclohexanediimine (H(2)salch), N,N'-bis(acetylacetone)cyclohexanediimine (H(2)acacch) and N,N'-bis(benzoylacetone)cyclohexanediimine (H(2)bzacch), were determined from their enthalpies of combustion and sublimation, obtained by static bomb calorimetry in oxygen and by the Knudsen effusion technique, respectively. The results are compared with identical parameters for related compounds previously studied, resulting from the condensation of salicylaldehyde or beta-diketone with aliphatic diamines.
