Cs2KVF6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Cs(1) is bonded to twelve equivalent F(1) atoms to form CsF12 cuboctahedra that share corners with twelve equivalent Cs(1)F12 cuboctahedra, faces with six equivalent Cs(1)F12 cuboctahedra, faces with four equivalent K(1)F6 octahedra, and faces with four equivalent V(1)F6 octahedra. K(1) is bonded to six equivalent F(1) atoms to form KF6 octahedra that share corners with six equivalent V(1)F6 octahedra and faces with eight equivalent Cs(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. V(1) is bonded to six equivalent F(1) atoms to form VF6 octahedra that share corners with six equivalent K(1)F6 octahedra and faces with eight equivalent Cs(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a distorted linear geometry to four equivalent Cs(1), one K(1), and one V(1) atom.
