Ho2VOs is Heusler structured and crystallizes in the trigonal R3m space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 8-coordinate geometry to four equivalent V(1) and four equivalent Os(1) atoms. There are three shorter (2.91 Å) and one longer (3.27 Å) Ho(1)-V(1) bond length. There are three shorter (2.91 Å) and one longer (3.27 Å) Ho(1)-Os(1) bond length. In the second Ho site, Ho(2) is bonded in a 1-coordinate geometry to one V(1) and four equivalent Os(1) atoms. The Ho(2)-V(1) bond length is 2.13 Å. There are three shorter (2.91 Å) and one longer (3.27 Å) Ho(2)-Os(1) bond length. V(1) is bonded in a distorted single-bond geometry to one Ho(2), four equivalent Ho(1), and three equivalent Os(1) atoms. All V(1)-Os(1) bond lengths are 3.16 Å. Os(1) is bonded in a 11-coordinate geometry to four equivalent Ho(1), four equivalent Ho(2), and three equivalent V(1) atoms.
