Sc2SO2 crystallizes in the hexagonal P6_3/mmc space group. Sc(1) is bonded in a 7-coordinate geometry to three equivalent S(1) and four equivalent O(1) atoms. S(1) is bonded to six equivalent Sc(1) atoms to form distorted SSc6 pentagonal pyramids that share corners with twelve equivalent O(1)Sc4 tetrahedra, edges with six equivalent S(1)Sc6 pentagonal pyramids, and edges with six equivalent O(1)Sc4 tetrahedra. O(1) is bonded to four equivalent Sc(1) atoms to form OSc4 tetrahedra that share corners with six equivalent S(1)Sc6 pentagonal pyramids, corners with six equivalent O(1)Sc4 tetrahedra, edges with three equivalent S(1)Sc6 pentagonal pyramids, and edges with three equivalent O(1)Sc4 tetrahedra.
Sc2SO2 crystallizes in the hexagonal P6_3/mmc space group. Sc(1) is bonded in a 7-coordinate geometry to three equivalent S(1) and four equivalent O(1) atoms. All Sc(1)-S(1) bond lengths are 2.72 Å. There are three shorter (2.11 Å) and one longer (2.16 Å) Sc(1)-O(1) bond length. S(1) is bonded to six equivalent Sc(1) atoms to form distorted SSc6 pentagonal pyramids that share corners with twelve equivalent O(1)Sc4 tetrahedra, edges with six equivalent S(1)Sc6 pentagonal pyramids, and edges with six equivalent O(1)Sc4 tetrahedra. O(1) is bonded to four equivalent Sc(1) atoms to form OSc4 tetrahedra that share corners with six equivalent S(1)Sc6 pentagonal pyramids, corners with six equivalent O(1)Sc4 tetrahedra, edges with three equivalent S(1)Sc6 pentagonal pyramids, and edges with three equivalent O(1)Sc4 tetrahedra.
