K2RuAuF6 is (Cubic) Perovskite-derived structured and 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 Ru(1)F6 octahedra, and faces with four equivalent Au(1)F6 octahedra. Ru(1) is bonded to six equivalent F(1) atoms to form RuF6 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 Ru(1)F6 octahedra and faces with eight equivalent K(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. F(1) is bonded to four equivalent K(1), one Ru(1), and one Au(1) atom to form a mixture of distorted face, corner, and edge-sharing FK4RuAu octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
