CaPrHfCrO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic F-43m space group. Ca(1) is bonded to twelve equivalent O(1) atoms to form CaO12 cuboctahedra that share corners with twelve equivalent Ca(1)O12 cuboctahedra, faces with six equivalent Pr(1)O12 cuboctahedra, faces with four equivalent Hf(1)O6 octahedra, and faces with four equivalent Cr(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 Ca(1)O12 cuboctahedra, faces with four equivalent Hf(1)O6 octahedra, and faces with four equivalent Cr(1)O6 octahedra. Hf(1) is bonded to six equivalent O(1) atoms to form HfO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra, faces with four equivalent Ca(1)O12 cuboctahedra, and faces with four equivalent Pr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Cr(1) is bonded to six equivalent O(1) atoms to form CrO6 octahedra that share corners with six equivalent Hf(1)O6 octahedra, faces with four equivalent Ca(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 Ca(1), two equivalent Pr(1), one Hf(1), and one Cr(1) atom.
