EuPrHfFeO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic F-43m 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 Pr(1)O12 cuboctahedra, faces with four equivalent Hf(1)O6 octahedra, and faces with four equivalent Fe(1)O6 octahedra. Pr(1) is bonded to twelve equivalent O(1) atoms to form PrO12 cuboctahedra that share corners with twelve equivalent Pr(1)O12 cuboctahedra, faces with six equivalent Eu(1)O12 cuboctahedra, faces with four equivalent Hf(1)O6 octahedra, and faces with four equivalent Fe(1)O6 octahedra. Hf(1) is bonded to six equivalent O(1) atoms to form HfO6 octahedra that share corners with six equivalent Fe(1)O6 octahedra, faces with four equivalent Eu(1)O12 cuboctahedra, and faces with four equivalent Pr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Fe(1) is bonded to six equivalent O(1) atoms to form FeO6 octahedra that share corners with six equivalent Hf(1)O6 octahedra, faces with four equivalent Eu(1)O12 cuboctahedra, and faces with four equivalent Pr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to two equivalent Eu(1), two equivalent Pr(1), one Hf(1), and one Fe(1) atom.
