The crystal structure described by SrEuS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Sr(1) is bonded to six equivalent S(1) atoms to form SrS6 octahedra that share corners with six equivalent Eu(1)S6 octahedra, edges with six equivalent Sr(1)S6 octahedra, and edges with six equivalent Eu(1)S6 octahedra. The corner-sharing octahedral tilt angles are 1°. Eu(1) is bonded to six equivalent S(1) atoms to form EuS6 octahedra that share corners with six equivalent Sr(1)S6 octahedra, edges with six equivalent Sr(1)S6 octahedra, and edges with six equivalent Eu(1)S6 octahedra. The corner-sharing octahedral tilt angles are 1°. S(1) is bonded to three equivalent Sr(1) and three equivalent Eu(1) atoms to form a mixture of corner and edge-sharing SSr3Eu3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
