CsMgF3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-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, and faces with eight equivalent Mg(1)F6 octahedra. Mg(1) is bonded to six equivalent F(1) atoms to form MgF6 octahedra that share corners with six equivalent Mg(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) and two equivalent Mg(1) atoms.
