The compound described by Dy2S3 is Stibnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 8-coordinate geometry to two equivalent S(2), three equivalent S(1), and three equivalent S(3) atoms. In the second Dy site, Dy(2) is bonded to two equivalent S(1), two equivalent S(3), and three equivalent S(2) atoms to form a mixture of distorted corner and edge-sharing DyS7 pentagonal bipyramids. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to two equivalent Dy(2) and three equivalent Dy(1) atoms. In the second S site, S(2) is bonded to two equivalent Dy(1) and three equivalent Dy(2) atoms to form a mixture of corner and edge-sharing SDy5 square pyramids. In the third S site, S(3) is bonded to two equivalent Dy(2) and three equivalent Dy(1) atoms to form a mixture of distorted corner and edge-sharing SDy5 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
