The back cover picture shows Steely alien is invading a lilac garden . A synthetic all‐metal cluster compound is shown computationally to possess five‐fold (π and σ) aromaticity, including d‐orbital aromaticity. The bottleable [Pd 3 Sn 8 Bi 6 ] 4 cluster features a core‐shell shape akin to an unidentified flying object (UFO), in which a triangular Pd3 core is largely floating inside a Sn 8 Bi 6 shell. Electron clouds in the system are delocalized over the Pd 3 core, trigonal pyramid Sn 4 caps, peripheral Bi 6 ring, and roof‐like Sn 2 Bi 2 walls, whose electron‐counting follows the (4 n + 2) Hückel rule. The finding is beyond imagination and should help appease debate on the nature of aromaticity in the community. More details are discussed in the article by Zhai et al. on page 126–130.
