Employing nucleus independent chemical shift (NICS) computations and according to the pattern of the NICS scan plot 4 on 3", the authors suggested that the molecule is a σ-aromatic species as it is reflected also in the title of their paper. Unfortunately, NICS is an inappropriate tool for evaluation of the magnetic aromaticity among early and mid-transition metals (TM), the elements that share a characteristic with thorium; they all have low-energy unoccupied orbitals. In the following we explain why NICS fails to assess aromaticity of molecules containing TMs and prove that the Th3 ring is a weakly antiaromatic system. We introduce a simple protocol to examine the aromaticity of any molecule utilizing software packages, which have been used by the authors of the main article.
