KPrHf2O6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. K(1) is bonded to twelve equivalent O(1) atoms to form KO12 cuboctahedra that share corners with twelve equivalent K(1)O12 cuboctahedra, faces with six equivalent Pr(1)O12 cuboctahedra, and faces with eight equivalent Hf(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 K(1)O12 cuboctahedra, and faces with eight equivalent Hf(1)O6 octahedra. Hf(1) is bonded to six equivalent O(1) atoms to form HfO6 octahedra that share corners with six equivalent Hf(1)O6 octahedra, faces with four equivalent K(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 K(1), two equivalent Pr(1), and two equivalent Hf(1) atoms.
