Na2CoAuF6 crystallizes in the cubic Fm-3m space group. Na(1) is bonded to twelve equivalent F(1) atoms to form distorted NaF12 cuboctahedra that share corners with twelve equivalent Na(1)F12 cuboctahedra, faces with six equivalent Na(1)F12 cuboctahedra, faces with four equivalent Co(1)F6 octahedra, and faces with four equivalent Au(1)F6 octahedra. Co(1) is bonded to six equivalent F(1) atoms to form CoF6 octahedra that share corners with six equivalent Au(1)F6 octahedra and faces with eight equivalent Na(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. Au(1) is bonded to six equivalent F(1) atoms to form AuF6 octahedra that share corners with six equivalent Co(1)F6 octahedra and faces with eight equivalent Na(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a distorted linear geometry to four equivalent Na(1), one Co(1), and one Au(1) atom.
