Not a bird, not a plane, perhaps a superatom: The term “superatom” has been used for “naked” metal atom clusters with a certain electronic structure. On the basis of structural data the question of whether this classification—the Jellium model—is a suitable description of a metalloid cluster with the same number of valence electrons is addressed. The picture shows the superatomic core of naked and ligand-bearing Ga atoms in the title cluster.
