The crystal structure described by CrHgF6 crystallizes in the trigonal R-3 space group. Cr(1) is bonded to six equivalent F(1) atoms to form CrF6 octahedra that share corners with six equivalent Hg(1)F6 octahedra. The corner-sharing octahedral tilt angles are 49°. Hg(1) is bonded to six equivalent F(1) atoms to form HgF6 octahedra that share corners with six equivalent Cr(1)F6 octahedra. The corner-sharing octahedral tilt angles are 49°. F(1) is bonded in a distorted bent 120 degrees geometry to one Cr(1) and one Hg(1) atom. is represented by the CIF file [CIF]
