Inorganic pentaprismane : The unusual structure of the anion [Co@Ge 10 ] 3− , which was obtained by the reaction of K 4 Ge 9 with [Co(C 8 H 12 )(C 8 H 13 )] in ethylenediamine, raises questions about chemical bonding in the anion. The Zintl ion cluster has virtual D 5 h symmetry and is a unique example of a ligand‐free cluster that is not a deltahedron. The delocalized chemical bonding is represented in the picture by one of the bonding orbitals of the anion.
