Golden cage : The two smallest anionic gold cages, Au 16 − and Au 17 − , are doped with a Cu atom to give the cluster anions CuAu 16 − (see picture) and CuAu 17 − , respectively. The photoelectron spectra of CuAu 16 − and CuAu 17 − suggest that the doping does not alter the structures of the parent cages. Theoretical studies confirm that the Cu atom resides in the center of the gold cages, similar to the situation with endohedral fullerenes.
