Dy2O2S crystallizes in the hexagonal P6_3/mmc space group. Dy(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 Dy(1) atoms to form distorted SDy6 pentagonal pyramids that share corners with twelve equivalent O(1)Dy4 tetrahedra, edges with six equivalent S(1)Dy6 pentagonal pyramids, and edges with six equivalent O(1)Dy4 tetrahedra. O(1) is bonded to four equivalent Dy(1) atoms to form ODy4 tetrahedra that share corners with six equivalent S(1)Dy6 pentagonal pyramids, corners with six equivalent O(1)Dy4 tetrahedra, edges with three equivalent S(1)Dy6 pentagonal pyramids, and edges with three equivalent O(1)Dy4 tetrahedra.
Dy2O2S crystallizes in the hexagonal P6_3/mmc space group. Dy(1) is bonded in a 7-coordinate geometry to three equivalent S(1) and four equivalent O(1) atoms. All Dy(1)-S(1) bond lengths are 2.89 Å. There are three shorter (2.25 Å) and one longer (2.29 Å) Dy(1)-O(1) bond length. S(1) is bonded to six equivalent Dy(1) atoms to form distorted SDy6 pentagonal pyramids that share corners with twelve equivalent O(1)Dy4 tetrahedra, edges with six equivalent S(1)Dy6 pentagonal pyramids, and edges with six equivalent O(1)Dy4 tetrahedra. O(1) is bonded to four equivalent Dy(1) atoms to form ODy4 tetrahedra that share corners with six equivalent S(1)Dy6 pentagonal pyramids, corners with six equivalent O(1)Dy4 tetrahedra, edges with three equivalent S(1)Dy6 pentagonal pyramids, and edges with three equivalent O(1)Dy4 tetrahedra.
