| Zusammenfassung: | © 2018 Wiley Periodicals, Inc. This study reports the spin-orbit effects on the aromaticity of the N5-, P5-, As5-, Sb5-, Bi5-, and Mc5- anionic clusters via the magnetically induced current-density method. All-electron density functional theory (DFT) calculations were carried out using the four-component Dirac-Coulomb (DC) hamiltonian, including scalar and spin-orbit relativistic effects. The magnetic index of aromaticity was calculated by numerical integration over the current flow between two atoms in the pentagonal ring. These values were compared to the spin-free values (spin-orbit coupling switched off), in order to assess the spin-orbit effect on aromaticity. It was found that in the heavy anions, Bi5- and Mc5-, there is a significant influence of the spin-orbit coupling. © 2018 Wiley Periodicals, Inc |
