Ho3Os is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 3-coordinate geometry to three equivalent Os(1) atoms. In the second Ho site, Ho(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Os(1) atoms. Os(1) is bonded in a 8-coordinate geometry to two equivalent Ho(2) and six equivalent Ho(1) atoms.
Ho3Os is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 3-coordinate geometry to three equivalent Os(1) atoms. There are a spread of Ho(1)-Os(1) bond distances ranging from 2.84-3.11 Å. In the second Ho site, Ho(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Os(1) atoms. There is one shorter (2.71 Å) and one longer (2.81 Å) Ho(2)-Os(1) bond length. Os(1) is bonded in a 8-coordinate geometry to two equivalent Ho(2) and six equivalent Ho(1) atoms.
