The material structure described by Ho5Ge4 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to two equivalent Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms to form corner-sharing HoGe6 octahedra. The corner-sharing octahedral tilt angles range from 51-53°. In the second Ho site, Ho(2) is bonded in a 7-coordinate geometry to one Ge(1), two equivalent Ge(2), and four equivalent Ge(3) atoms. In the third Ho site, Ho(3) is bonded in a 6-coordinate geometry to one Ge(2), two equivalent Ge(1), and three equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Ho(1), two equivalent Ho(2), four equivalent Ho(3), and one Ge(2) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Ho(1), two equivalent Ho(3), four equivalent Ho(2), and one Ge(1) atom. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to one Ho(1), three equivalent Ho(3), and four equivalent Ho(2) atoms. is represented by the CIF file [CIF]
