Ho2OsGe2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 8-coordinate geometry to two equivalent Os(1), one Ge(2), and five equivalent Ge(1) atoms. In the second Ho site, Ho(2) is bonded in a 10-coordinate geometry to four equivalent Os(1), two equivalent Ge(1), and four equivalent Ge(2) atoms. Os(1) is bonded in a 10-coordinate geometry to two equivalent Ho(1), four equivalent Ho(2), one Ge(1), and three equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Ho(2), five equivalent Ho(1), one Os(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to one Ho(1), four equivalent Ho(2), three equivalent Os(1), and one Ge(2) atom.
Ho2OsGe2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 8-coordinate geometry to two equivalent Os(1), one Ge(2), and five equivalent Ge(1) atoms. Both Ho(1)-Os(1) bond lengths are 3.17 Å. The Ho(1)-Ge(2) bond length is 2.88 Å. There are a spread of Ho(1)-Ge(1) bond distances ranging from 3.02-3.21 Å. In the second Ho site, Ho(2) is bonded in a 10-coordinate geometry to four equivalent Os(1), two equivalent Ge(1), and four equivalent Ge(2) atoms. There are two shorter (3.08 Å) and two longer (3.16 Å) Ho(2)-Os(1) bond lengths. Both Ho(2)-Ge(1) bond lengths are 2.91 Å. There are two shorter (3.02 Å) and two longer (3.11 Å) Ho(2)-Ge(2) bond lengths. Os(1) is bonded in a 10-coordinate geometry to two equivalent Ho(1), four equivalent Ho(2), one Ge(1), and three equivalent Ge(2) atoms. The Os(1)-Ge(1) bond length is 2.60 Å. There are two shorter (2.45 Å) and one longer (2.52 Å) Os(1)-Ge(2) bond length. There are two inequivalent Ge sites.
