MgOSrO 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 Mg(1)O6 octahedra, edges with six equivalent Sr(1)O6 octahedra, and edges with six equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles are 8°. Mg(1) is bonded to six equivalent O(1) atoms to form MgO6 octahedra that share corners with six equivalent Sr(1)O6 octahedra, edges with six equivalent Sr(1)O6 octahedra, and edges with six equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles are 8°. O(1) is bonded to three equivalent Sr(1) and three equivalent Mg(1) atoms to form a mixture of edge and corner-sharing OSr3Mg3 octahedra. The corner-sharing octahedra are not tilted.
