The crystal structure described by K2FeAuF6 crystallizes in the cubic Fm-3m space group. K(1) is bonded to twelve equivalent F(1) atoms to form KF12 cuboctahedra that share corners with twelve equivalent K(1)F12 cuboctahedra, faces with six equivalent K(1)F12 cuboctahedra, faces with four equivalent Fe(1)F6 octahedra, and faces with four equivalent Au(1)F6 octahedra. Fe(1) is bonded to six equivalent F(1) atoms to form FeF6 octahedra that share corners with six equivalent Au(1)F6 octahedra and faces with eight equivalent K(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 Fe(1)F6 octahedra and faces with eight equivalent K(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a 6-coordinate geometry to four equivalent K(1), one Fe(1), and one Au(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
