The crystal structure described by Sm(DyS2)2 crystallizes in the tetragonal I-42d space group. Dy(1) is bonded to eight equivalent S(1) atoms to form distorted DyS8 hexagonal bipyramids that share corners with four equivalent Dy(1)S8 hexagonal bipyramids, corners with four equivalent Sm(1)S8 hexagonal bipyramids, edges with four equivalent Dy(1)S8 hexagonal bipyramids, faces with four equivalent Dy(1)S8 hexagonal bipyramids, and faces with four equivalent Sm(1)S8 hexagonal bipyramids. Sm(1) is bonded to eight equivalent S(1) atoms to form distorted SmS8 hexagonal bipyramids that share corners with eight equivalent Dy(1)S8 hexagonal bipyramids, edges with four equivalent Sm(1)S8 hexagonal bipyramids, and faces with eight equivalent Dy(1)S8 hexagonal bipyramids. S(1) is bonded to four equivalent Dy(1) and two equivalent Sm(1) atoms to form a mixture of distorted corner, face, and edge-sharing SSm2Dy4 octahedra. The corner-sharing octahedral tilt angles range from 17-50°. is represented by the Crystallographic Information File (CIF) [CIF]
