The structure described by Dy5Ir3 crystallizes in the tetragonal P4/ncc space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to two equivalent Ir(2) and three equivalent Ir(1) atoms to form distorted DyIr5 trigonal bipyramids that share corners with four equivalent Dy(2)Ir4 tetrahedra, corners with eleven equivalent Dy(1)Ir5 trigonal bipyramids,  an edgeedge with one Dy(2)Ir4 tetrahedra, edges with six equivalent Dy(1)Ir5 trigonal bipyramids, and faces with two equivalent Dy(1)Ir5 trigonal bipyramids. In the second Dy site, Dy(2) is bonded to four equivalent Ir(1) atoms to form DyIr4 tetrahedra that share corners with sixteen equivalent Dy(1)Ir5 trigonal bipyramids, edges with two equivalent Dy(2)Ir4 tetrahedra, and edges with four equivalent Dy(1)Ir5 trigonal bipyramids. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 8-coordinate geometry to two equivalent Dy(2) and six equivalent Dy(1) atoms. In the second Ir site, Ir(2) is bonded in a 8-coordinate geometry to eight equivalent Dy(1) atoms. is represented by the CIF card [CIF]
