The compound described by EuYO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Eu(1) is bonded to six equivalent O(1) atoms to form EuO6 octahedra that share corners with six equivalent Y(1)O6 octahedra, edges with six equivalent Eu(1)O6 octahedra, and edges with six equivalent Y(1)O6 octahedra. The corner-sharing octahedral tilt angles are 8°. Y(1) is bonded to six equivalent O(1) atoms to form YO6 octahedra that share corners with six equivalent Eu(1)O6 octahedra, edges with six equivalent Eu(1)O6 octahedra, and edges with six equivalent Y(1)O6 octahedra. The corner-sharing octahedral tilt angles are 8°. O(1) is bonded to three equivalent Eu(1) and three equivalent Y(1) atoms to form a mixture of corner and edge-sharing OEu3Y3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
