The material described by Dy5Au2Bi crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a distorted trigonal planar geometry to one Au(1) and two equivalent Bi(1) atoms. In the second Dy site, Dy(2) is bonded in a square co-planar geometry to four equivalent Au(1) atoms. Au(1) is bonded to two equivalent Dy(1), two equivalent Dy(2), and one Au(1) atom to form distorted corner-sharing AuDy4Au trigonal bipyramids. Bi(1) is bonded in a 8-coordinate geometry to eight equivalent Dy(1) atoms. is represented by the CIF card [CIF]
