The obtained data are needed for evaluation of reactivity of Nh studied by gas-phase chromatography experiments. Results show that Nh should be less reactive (or more volatile) than Tl, both with respect to gold and the hydroxyl group. The reason for that are strong relativistic effects on the valence 7s and 7p electron shells. In difference to the atoms, NhOH may be less volatile than TlOH due to its larger both dipole moment and anisotropic polarizability URL Link na plný text Public work category ADC No. of Archival Copy 42181 Catal.org.

Source document The Journal of Chemical Physics. Vol. 146, no. 18 (2017), art. no. 184306. - New York : American Institute of Physics, 2017 Keywords karbonylové zlúčeniny tetrakarbonyly - tetracarbonyls pentakarbonyly - pentacarbonyls Language English Country United States of America systematics 544 Annotation Calculations of the electronic structures and properties of M(CO)(5) and M(CO)(4), where M = Ru, Os, and Hs, have been performed using a variety of relativistic methods such as density functional theory and Dirac-Coulomb correlated ones implemented in program packages such as ADF, DIRAC, and ReSpect. The obtained results show that trends in spectroscopic properties of the M(CO)(5) species in group 8 follow the same pattern as that of other compounds of group 4 through group 8 elements. The calculated first M-CO bond dissociation energy (FBDE) of Hs(CO)(5) turned out to be significantly weaker than that of Os(CO)(5). This was obtained both at the scalar relativistic and spin-orbit levels of theory. The reason for that is the relativistic destabilization and the expansion of the 6d AOs, responsible for weaker sigma-forth and pi-back donations in the Hs compound. Thus, the FBDEs of M(CO)(5) have a Lambda-shape behavior in the row Ru-Os-Hs. The non-relativistic FBDEs steadily increase in this row. Using the results of the molecular calculations and a molecule-slab dispersion interaction model, the volatility of the group-8 carbonyls was estimated as adsorption enthalpies, Delta H-ads, on surfaces of quartz and Teflon used in gas-phase chromatography experiments. It was found that Hs(CO)(5) should be almost as volatile as the homologs; however, its interaction strength with these surfaces should be somewhat larger than that of both Ru(CO)(5) and Os(CO)(5), while the M(CO)(4) (M = Ru, Os, and Hs) molecules should be non-volatile. It will, therefore, be difficult to distinguish between group-8 M(CO)(5) species by measurements of their volatility as Delta H-ads on inert surfaces with error bars of similar to 4 kJ/mol.
