A sodium‐containing icosahedral quasicrystalline phase has been discovered. In their Communication page 12699 ff., G. J. Miller et al. describe the characterization of a Bergman‐type i ‐Na 13 Au 12 Ga 15 system. The existence and stability of this Na‐containing icosahedral quasicrystal is tightly linked to its substantial Au content, which allows the electron‐to‐atom value to satisfy a Hume–Rothery stabilization rule, and creates novel Na–Au polar‐covalent interactions.
