The fullerenes are the first “free-standing” elemental hollow cages identified by spectroscopy experiments and synthesized in the bulk. Here we report experimental and theoretical evidence of hollow cages consisting of pure metal atoms, Aun ¯ (n = 16-18), which, to our knowledge, are the first free-standing metal hollow cages detected in the laboratory. These hollow golden cages have an average diameter larger than 6 Å, which can easily hold one foreign atom inside.
