Vaporization of the barium molecular complex [Ba(18C6)(C5O2F6H)2] and the newly prepared strontium complex [Sr(15C5)(C5O2F6H)2] was studied using a semiempirical structure-thermochemical approach. The studies of intermolecular steric shielding of individual atoms and analysis of the possible intermolecular contacts in these complexes made it possible to identify the atoms and atom groups with significant contributions to the vaporization enthalpy. The hypothetical vaporization enthalpies were calculated by summing the contributions of groups. The melting and sublimation enthalpies were determined experimentally. |
