Dy2Te crystallizes in the orthorhombic Pnma space group. There are six inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 3-coordinate geometry to one Te(3) and two equivalent Te(1) atoms. In the second Dy site, Dy(2) is bonded to one Te(2), two equivalent Te(1), and two equivalent Te(3) atoms to form a mixture of distorted corner and edge-sharing DyTe5 square pyramids. In the third Dy site, Dy(3) is bonded in a 4-coordinate geometry to one Te(2) and three equivalent Te(3) atoms. In the fourth Dy site, Dy(4) is bonded to two equivalent Te(2) and three equivalent Te(1) atoms to form a mixture of distorted corner and edge-sharing DyTe5 trigonal bipyramids. In the fifth Dy site, Dy(5) is bonded in a 4-coordinate geometry to two equivalent Te(2) and two equivalent Te(3) atoms. In the sixth Dy site, Dy(6) is bonded in a distorted L-shaped geometry to one Te(1) and one Te(2) atom. There are three inequivalent Te sites. In the first Te site, Te(3) is bonded in a 8-coordinate geometry to one Dy(1), two equivalent Dy(2), two equivalent Dy(5), and three equivalent Dy(3) atoms. In the second Te site, Te(1) is bonded in a 8-coordinate geometry to one Dy(6), two equivalent Dy(1), two equivalent Dy(2), and three equivalent Dy(4) atoms. In the third Te site, Te(2) is bonded to one Dy(2), one Dy(3), one Dy(6), two equivalent Dy(4), and two equivalent Dy(5) atoms to form distorted edge-sharing TeDy7 pentagonal bipyramids.
