The material described by (Na)2HgAsF6 crystallizes in the cubic Fm-3m space group. The structure consists of eight 7440-23-5 atoms inside a HgAsF6 framework. In the HgAsF6 framework, Hg(1) is bonded to six equivalent F(1) atoms to form HgF6 octahedra that share corners with six equivalent As(1)F6 octahedra. The corner-sharing octahedra are not tilted. As(1) is bonded to six equivalent F(1) atoms to form AsF6 octahedra that share corners with six equivalent Hg(1)F6 octahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a distorted linear geometry to one Hg(1) and one As(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
