AcFeO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Ac(1) is bonded to twelve equivalent O(1) atoms to form AcO12 cuboctahedra that share corners with twelve equivalent Ac(1)O12 cuboctahedra, faces with six equivalent Ac(1)O12 cuboctahedra, and faces with eight equivalent Fe(1)O6 octahedra. Fe(1) is bonded to six equivalent O(1) atoms to form FeO6 octahedra that share corners with six equivalent Fe(1)O6 octahedra and faces with eight equivalent Ac(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to four equivalent Ac(1) and two equivalent Fe(1) atoms.
