Ho5Au2Sb crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to four equivalent Au(1) and two equivalent Sb(1) atoms to form corner-sharing HoSb2Au4 octahedra. The corner-sharing octahedral tilt angles range from 0-49°. In the second Ho site, Ho(2) is bonded in a 5-coordinate geometry to three equivalent Au(1) and two equivalent Sb(1) atoms. Au(1) is bonded in a 8-coordinate geometry to two equivalent Ho(1) and six equivalent Ho(2) atoms. Sb(1) is bonded in a distorted q6 geometry to two equivalent Ho(1) and eight equivalent Ho(2) atoms.

In the first Ho site, Ho(1) is bonded to four equivalent Au(1) and two equivalent Sb(1) atoms to form corner-sharing HoSb2Au4 octahedra. The corner-sharing octahedral tilt angles range from 0-49°. All Ho(1)-Au(1) bond lengths are 3.14 Å. Both Ho(1)-Sb(1) bond lengths are 3.23 Å. In the second Ho site, Ho(2) is bonded in a 5-coordinate geometry to three equivalent Au(1) and two equivalent Sb(1) atoms. There is one shorter (2.99 Å) and two longer (3.00 Å) Ho(2)-Au(1) bond lengths. Both Ho(2)-Sb(1) bond lengths are 3.35 Å. Au(1) is bonded in a 8-coordinate geometry to two equivalent Ho(1) and six equivalent Ho(2) atoms. Sb(1) is bonded in a distorted q6 geometry to two equivalent Ho(1) and eight equivalent Ho(2) atoms.
