Sr(SmS2)2 crystallizes in the tetragonal I-42d space group. Sr(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. Sm(1) is bonded to eight equivalent S(1) atoms to form a mixture of distorted edge, corner, and face-sharing SmS8 hexagonal bipyramids. S(1) is bonded to two equivalent Sr(1) and four equivalent Sm(1) atoms to form a mixture of distorted edge, corner, and face-sharing SSr2Sm4 octahedra. The corner-sharing octahedral tilt angles range from 16-50°.
Sr(SmS2)2 crystallizes in the tetragonal I-42d space group. Sr(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. There are four shorter (2.94 Å) and four longer (3.13 Å) Sr(1)-S(1) bond lengths. Sm(1) is bonded to eight equivalent S(1) atoms to form a mixture of distorted edge, corner, and face-sharing SmS8 hexagonal bipyramids. There are a spread of Sm(1)-S(1) bond distances ranging from 2.81-3.11 Å. S(1) is bonded to two equivalent Sr(1) and four equivalent Sm(1) atoms to form a mixture of distorted edge, corner, and face-sharing SSr2Sm4 octahedra. The corner-sharing octahedral tilt angles range from 16-50°.
