When Kekulé first pictured the ring structure of benzene, hardly anyone could have imagined that electron delocalization and aromaticity may play a central role in an incredible variety of inorganic rings and 3D clusters containing s-, d-and even f-block metal atoms. Very recently, Boronski et al. designed and isolated under normal experimental conditions the crystalline actinide cluster [{Th(η 8 -C8H8)(μ3-Cl)2}3{K(THF)2}2]∞ containing at its heart the tri-thorium ring with a pair of uniformly distributed electrons. This discovery has been hailed for extending the range of the aromaticity concept to the record seventh row of the periodic table, and it has been suggested that aromaticity can be an important factor in the design of stable complexes with actinide-actinide bonds (which have previously been reported to be very weak and localized). The follow-up investigations revealed that the experimental data and the results of calculations of the magnetic criteria of aromaticity do not provide solid proves for the existence of the aromatic tri-thorium bond, and the unique multicenter charge-shift bonding (ThCl2)3 was shown to be the actual factor determining high symmetry (D3h) and exceptional stability of the crystalline actinide cluster. Very recently, Lin and Mo provided further computational data supporting the chargeshift bonding in the actinide cluster, and found that the overall charge transfer between thorium and chlorine atoms is about ten times more stabilizing than electron delocalization in the Th3 ring. The authors linked the latter with the stabilization effect resulting from the periodic boundary conditions (PBC) for the electron distribution, and made the conclusion that the trithorium bonding is therefore "truly delocalized and σ-aromatic". Similar conclusions were drawn by Tomeček et al. who utilized the entire arsenal of sophisticated computational methods to demonstrate that the Th3 ring contains cyclically delocalized electrons and should be regarded σ-aromatic. However, in both works the simplified highly ionized model cluster Th3Cl6 4+ was investigated, in which the electron binding energy associated with the highest occupied molecular orbital (HOMO) is incomparably higher in magnitude than in the neutral crystalline cluster. This leads to exaggeration of σ-bonding and charge delocalization between thorium atoms making the conclusions by Lin and Mo, and Tomeček et al. not directly transferable to Th3 in the isolated compound.
