The compound described by Eu2CeCrO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-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, faces with four equivalent Ce(1)O6 octahedra, and faces with four equivalent Cr(1)O6 octahedra. Ce(1) is bonded to six equivalent O(1) atoms to form CeO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra and faces with eight equivalent Eu(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 Ce(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), one Ce(1), and one Cr(1) atom. is represented by the CIF card [CIF]
