The material described by Ho3Ir2Ge3 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 11-coordinate geometry to four equivalent Ir(1), two equivalent Ge(1), and five equivalent Ge(2) atoms. In the second Ho site, Ho(2) is bonded in a 9-coordinate geometry to four equivalent Ir(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. Ir(1) is bonded in a 10-coordinate geometry to two equivalent Ho(2), four equivalent Ho(1), 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 three equivalent Ho(2), four equivalent Ho(1), and two equivalent Ir(1) atoms. In the second Ge site, Ge(2) is bonded in a 10-coordinate geometry to one Ho(2), five equivalent Ho(1), three equivalent Ir(1), and one Ge(2) atom. is represented by the CIF file [CIF]
