The crystal structure described by Dy5Pt2Sb crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to four equivalent Pt(1) and two equivalent Sb(1) atoms to form distorted corner-sharing DySb2Pt4 octahedra. The corner-sharing octahedral tilt angles range from 0-48°. In the second Dy site, Dy(2) is bonded in a 5-coordinate geometry to three equivalent Pt(1) and two equivalent Sb(1) atoms. Pt(1) is bonded in a 8-coordinate geometry to two equivalent Dy(1) and six equivalent Dy(2) atoms. Sb(1) is bonded in a distorted q6 geometry to two equivalent Dy(1) and eight equivalent Dy(2) atoms. is represented by the CIF card [CIF]
