The crystal structure described by Ho5Ir3 crystallizes in the tetragonal P4/ncc space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to two equivalent Ir(2) and three equivalent Ir(1) atoms to form distorted HoIr5 trigonal bipyramids that share corners with four equivalent Ho(2)Ir4 tetrahedra, corners with eleven equivalent Ho(1)Ir5 trigonal bipyramids,  an edgeedge with one Ho(2)Ir4 tetrahedra, edges with six equivalent Ho(1)Ir5 trigonal bipyramids, and faces with two equivalent Ho(1)Ir5 trigonal bipyramids. In the second Ho site, Ho(2) is bonded to four equivalent Ir(1) atoms to form HoIr4 tetrahedra that share corners with sixteen equivalent Ho(1)Ir5 trigonal bipyramids, edges with two equivalent Ho(2)Ir4 tetrahedra, and edges with four equivalent Ho(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 Ho(2) and six equivalent Ho(1) atoms. In the second Ir site, Ir(2) is bonded in a 8-coordinate geometry to eight equivalent Ho(1) atoms. is represented by the CIF file [CIF]
