The compound described by Dy7(PtTe)2 crystallizes in the orthorhombic Imm2 space group. There are four inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 5-coordinate geometry to two equivalent Pt(1), one Te(2), and two equivalent Te(1) atoms. In the second Dy site, Dy(2) is bonded in a 4-coordinate geometry to three equivalent Pt(1) and one Te(1) atom. In the third Dy site, Dy(3) is bonded in a 4-coordinate geometry to two equivalent Pt(1) and two equivalent Te(2) atoms. In the fourth Dy site, Dy(4) is bonded in a 3-coordinate geometry to one Te(2) and two equivalent Te(1) atoms. Pt(1) is bonded in a 7-coordinate geometry to two equivalent Dy(1), two equivalent Dy(3), and three equivalent Dy(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 8-coordinate geometry to two equivalent Dy(2), two equivalent Dy(4), and four equivalent Dy(1) atoms. In the second Te site, Te(2) is bonded in a 7-coordinate geometry to one Dy(4), two equivalent Dy(1), and four equivalent Dy(3) atoms. is represented by the CIF card [CIF]
