FeAsO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Fe(1) is bonded to twelve equivalent O(1) atoms to form FeO12 cuboctahedra that share corners with twelve equivalent Fe(1)O12 cuboctahedra, faces with six equivalent Fe(1)O12 cuboctahedra, and faces with eight equivalent As(1)O6 octahedra. As(1) is bonded to six equivalent O(1) atoms to form AsO6 octahedra that share corners with six equivalent As(1)O6 octahedra and faces with eight equivalent Fe(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to four equivalent Fe(1) and two equivalent As(1) atoms.
