EuNdHfTiO6 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 Nd(1)O12 cuboctahedra, faces with four equivalent Hf(1)O6 octahedra, and faces with four equivalent Ti(1)O6 octahedra. Nd(1) is bonded to twelve equivalent O(1) atoms to form NdO12 cuboctahedra that share corners with twelve equivalent Nd(1)O12 cuboctahedra, faces with six equivalent Eu(1)O12 cuboctahedra, faces with four equivalent Hf(1)O6 octahedra, and faces with four equivalent Ti(1)O6 octahedra. Hf(1) is bonded to six equivalent O(1) atoms to form HfO6 octahedra that share corners with six equivalent Ti(1)O6 octahedra, faces with four equivalent Eu(1)O12 cuboctahedra, and faces with four equivalent Nd(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Ti(1) is bonded to six equivalent O(1) atoms to form TiO6 octahedra that share corners with six equivalent Hf(1)O6 octahedra, faces with four equivalent Eu(1)O12 cuboctahedra, and faces with four equivalent Nd(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 Nd(1), one Hf(1), and one Ti(1) atom.
