The 5d core electrons of Hg become active and involved in forming chemical bonds under high pressure. In their Communication on page 9280 ff., M.‐S. Miao and co‐workers show by means of first‐principles calculations that Hg can form stable compounds of HgF 4 and HgF 3 under high pressure. The HgF 4 molecular crystal consists of square‐planar HgF 4 molecules. HgF 3 is an extended solid and exhibits exotic properties. It is metallic, ferromagnetic, and transparent to visible light.
