Temperature dependence of saturated vapor pressure has been measured by gas saturation technique for volatile bis-chelates of palladium(II) with such ligands as acetylacetone, hexafluoroacetylacetone, diethyldithiocarbamate, diisopropyldithiophosphate, and also mixed ligand complex with acetylacetone and cyclooctadiene-2,4. Standard thermodynamic parameters of vaporization Delta H-T(0) and Delta S-T(0) were calculated. Crystal molecular packings and intermolecular interactions were analyzed basing on structural data. Atom-atom potential calculation of van der Waals energy E-cryst in crystal lattice was performed and compared to the experimentally obtained values of sublimation enthalpy for the complexes under study.
