EuPmO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Eu(1) is bonded to twelve equivalent O(1) atoms to form EuO12 cuboctahedra that share corners with twelve equivalent Eu(1)O12 cuboctahedra, faces with six equivalent Eu(1)O12 cuboctahedra, and faces with eight equivalent Pm(1)O6 octahedra. Pm(1) is bonded to six equivalent O(1) atoms to form PmO6 octahedra that share corners with six equivalent Pm(1)O6 octahedra and faces with eight equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to four equivalent Eu(1) and two equivalent Pm(1) atoms.
