Resumen

The Oh-[Au6]2+ cluster exhibits an open-shell 1s21p2 which trend to a more stable D2 h isomer in 31.5 kcal/mol, as observed in the experimental [Au6{P(C6H4Me-o)pH2}6] cluster. By taking into account the spin-orbit coupling (SOC) in Oh-[Au6]2+, a resulting 1s1/2 21p1/2 2 closed-shell superatomic configuration is obtained stabilizing such structure by about 14.7 kcal/mol, decreasing the isomerization barrier. Thus, the spin-orbit term favors the Oh ↔ D2 h conformation rearrangement depicting a decrease in the calculated energy difference between both conformations, an interesting consequence which is not obtained in the hypothetical lighter counterparts.
