Abstract

The results of this Letter reveals that the [Re ₃(μ-Cl) ₃Cl ₉] ^3-, [Re ₃(μ-Br) ₃Br ₉] ^3-, [Re ₃(μ-I) ₃I ₉] ^3- clusters exhibit aromaticity and that spin-orbit effect decreases the aromaticity due to the fact that the 5d _3/2 spinors are more contracted than the scalar 5d orbitals. The [Re ₃(μ-I) ₃I ₉] ^3- and [Re ₃(μ-Br) ₃Br ₉] ^3- clusters are the most aromatic clusters. This can be explained by the np _1/2 and np _3/2 spinors radial expectation (〈r〉) values which follows the Cl < Br < I sequence. Thus, the most extended spinors correspond to I and Br ligands, as indicated in the ELF plots. Furthermore we carried out TDDFT calculations which agrees with the fact that [Re ₃(μ-I) ₃I ₉] ^3- should show the highest value of aromaticity.
