Finally, the authors seem confident in the numbers provided to confirm the 'magnetic aromaticity' in the elongated prism Bi6 2-and the isolated clusters. Negative values of the nucleus independent chemical shift (NICS) are indeed reliable indicators of aromaticity in the planar organic rings with π-conjugated bonds. However, for topologically diversified systems the magnetic-response criteria of aromaticity like NICS are often difficult to interpret if we do not distinguish between the chemically meaningful aromatic currents and the artifactual interferences of the local currents (cf., the case of the P4 and Si4 4-tetrahedrons). Unfortunately, in the case of the elongated prism Bi6 2-, we face this problem (Figure ). Molecular orbital decomposition of the magnetic shielding in the centroid of the Bi6 2-prism and the isolated clusters reveals that negative values of NICS reported by Peerless et al. come mostly from the local induced currents generated by six 6s-type lone pairs surrounding the prism, and hence they can by no means be associated with aromaticity (see Supporting Information for more details). Moreover, the authors should bear in mind that in the external magnetic field electrons occupying the outermost energy levels (HOMO, HOMO-1, etc.) always 'circulate' more intensively over the ring/cage than the electrons occupying inner MOs (cf. the Fowler-Steiner theory). For this reason, the induced current associated with the transannular bonding HOMO-9 in Bi6 2-is too weak to interfere and cancel the strong net current associated with the transannular antibonding φ-type HOMO (Figure ). Consequently, the effective non-bonding character of the pair of orbitals a1ˈ and a2ˈ is magnetically decoupled leading to the artifactual diatropic net currents in the {Bi3} units that mimic the aromatic ring currents, but in fact they carry no chemically meaningful information about the resonance electronic structure and aromatic stabilization.
