The compound described by EuY2O4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Eu(1) is bonded to four equivalent O(1) atoms to form EuO4 tetrahedra that share corners with twelve equivalent Y(1)O6 octahedra. The corner-sharing octahedral tilt angles are 60°. Y(1) is bonded to six equivalent O(1) atoms to form YO6 octahedra that share corners with six equivalent Eu(1)O4 tetrahedra and edges with six equivalent Y(1)O6 octahedra. O(1) is bonded to one Eu(1) and three equivalent Y(1) atoms to form a mixture of distorted corner and edge-sharing OEuY3 tetrahedra. is represented by the CIF file [CIF]
