The crystal structure described by BaO(SrO) is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Ba(1) is bonded to six equivalent O(1) atoms to form BaO6 octahedra that share corners with six equivalent Sr(1)O6 octahedra, edges with six equivalent Ba(1)O6 octahedra, and edges with six equivalent Sr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 4°. Sr(1) is bonded to six equivalent O(1) atoms to form SrO6 octahedra that share corners with six equivalent Ba(1)O6 octahedra, edges with six equivalent Ba(1)O6 octahedra, and edges with six equivalent Sr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 4°. O(1) is bonded to three equivalent Ba(1) and three equivalent Sr(1) atoms to form a mixture of corner and edge-sharing OBa3Sr3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
