Our all-electron fully relativistic Dirac–Fock (DF) and nonrelativistic (NR) Hartree–Fock SCF molecular calculations for the superheavy tetrahedral (Td) oganesson tetratennesside OgTs 4 predict atomization energies (A e ) of 7.45 and −11.21 eV, respectively. Our DF and NR calculations, however for the square planar (D 4h ) OgTs 4 predict atomization energies (A e ) of 6.34 and −8.56 eV, respectively. There are dramatic relativistic effects for the atomization energies of T d and D 4h OgTs 4 of…
