Ho5Ir2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 2-coordinate geometry to three equivalent Ir(1) atoms. In the second Ho site, Ho(3) is bonded to four equivalent Ir(1) atoms to form distorted edge-sharing HoIr4 tetrahedra. In the third Ho site, Ho(2) is bonded in a 3-coordinate geometry to three equivalent Ir(1) atoms. Ir(1) is bonded in a 8-coordinate geometry to two equivalent Ho(3), three equivalent Ho(1), and three equivalent Ho(2) atoms.
Ho5Ir2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 2-coordinate geometry to three equivalent Ir(1) atoms. There are a spread of Ho(1)-Ir(1) bond distances ranging from 2.73-3.31 Å. In the second Ho site, Ho(3) is bonded to four equivalent Ir(1) atoms to form distorted edge-sharing HoIr4 tetrahedra. There are two shorter (2.87 Å) and two longer (2.93 Å) Ho(3)-Ir(1) bond lengths. In the third Ho site, Ho(2) is bonded in a 3-coordinate geometry to three equivalent Ir(1) atoms. There are a spread of Ho(2)-Ir(1) bond distances ranging from 2.85-3.01 Å. Ir(1) is bonded in a 8-coordinate geometry to two equivalent Ho(3), three equivalent Ho(1), and three equivalent Ho(2) atoms.
