Sr4SO3 is Caswellsilverite-like structured and crystallizes in the cubic Pm-3m space group. There are four inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to six equivalent O(1) atoms to form SrO6 octahedra that share corners with six equivalent Sr(1)O6 octahedra and edges with twelve Sr(2,2,2)S2O4 octahedra. The corner-sharing octahedra are not tilted. In the second Sr site, Sr(2) is bonded to two equivalent S(1) and four equivalent O(1) atoms to form SrS2O4 octahedra that share corners with six equivalent Sr(2)S2O4 octahedra; edges with four equivalent Sr(1)O6 octahedra; and edges with eight Sr(2,2)S2O4 octahedra. The corner-sharing octahedra are not tilted. In the third Sr site, Sr(2) is bonded to two equivalent S(1) and four equivalent O(1) atoms to form SrS2O4 octahedra that share corners with six equivalent Sr(2)S2O4 octahedra; edges with four equivalent Sr(1)O6 octahedra; and edges with eight Sr(2,2)S2O4 octahedra. The corner-sharing octahedra are not tilted. In the fourth Sr site, Sr(2) is bonded to two equivalent S(1) and four equivalent O(1) atoms to form SrS2O4 octahedra that share corners with six equivalent Sr(2)S2O4 octahedra; edges with four equivalent Sr(1)O6 octahedra; and edges with eight Sr(2,2)S2O4 octahedra. The corner-sharing octahedra are not tilted. S(1) is bonded to six Sr(2,2,2) atoms to form SSr6 octahedra that share corners with six equivalent S(1)Sr6 octahedra and edges with twelve equivalent O(1)Sr6 octahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to two equivalent Sr(1) and four Sr(2,2) atoms to form OSr6 octahedra that share corners with six equivalent O(1)Sr6 octahedra, edges with four equivalent S(1)Sr6 octahedra, and edges with eight equivalent O(1)Sr6 octahedra. The corner-sharing octahedra are not tilted.
