- Abstract
- The sublimation enthalpy of beryllium (II), aluminium (III), chromium (III), iron (III), cobalt (III), nickel (II), copper (II), oxovanadium (IV) and zirconium (IV) 2,4 -pentanedionate complexes has been determined by vacuum Differential Scanning Calorimetry (DSC), subsequent to benzoic acid being proposed as calibrant for this technique. In conjunction with existing thermochemical data for these complexes, metal-ligand homolytic bond dissociation energies are calculated and are rationalized in terms of the ionic size of the coordinated meta and the crystal field stabilization energies for the complex. Old and new methods for the determination of sublimation enthalpy are reviewed and the present data collectively reveal the versatility and precision of DSC fort the direct determination of sublimation enthalpies of metal complexes. The new sublimation enthalpy data presented for metal 2-4- pentanedionate complexes effectively ends the controversy associated with the previously reported corresponding data/; Master of Applied Science
