Ho3Ru 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 Ru(1) atoms. In the second Ho site, Ho(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Ru(1) atoms. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Ho(2) and six equivalent Ho(1) atoms.
Ho3Ru 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 Ru(1) atoms. There are a spread of Ho(1)-Ru(1) bond distances ranging from 2.84-3.19 Å. In the second Ho site, Ho(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Ru(1) atoms. There is one shorter (2.74 Å) and one longer (2.78 Å) Ho(2)-Ru(1) bond length. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Ho(2) and six equivalent Ho(1) atoms.
