SrEuO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Sr(1) is bonded to six equivalent O(1) atoms to form SrO6 octahedra that share corners with six equivalent Eu(1)O6 octahedra, edges with six equivalent Sr(1)O6 octahedra, and edges with six equivalent Eu(1)O6 octahedra. The corner-sharing octahedral tilt angles are 1°. Eu(1) is bonded to six equivalent O(1) atoms to form EuO6 octahedra that share corners with six equivalent Sr(1)O6 octahedra, edges with six equivalent Sr(1)O6 octahedra, and edges with six equivalent Eu(1)O6 octahedra. The corner-sharing octahedral tilt angles are 1°. O(1) is bonded to three equivalent Sr(1) and three equivalent Eu(1) atoms to form a mixture of corner and edge-sharing OSr3Eu3 octahedra. The corner-sharing octahedra are not tilted.
