The material described by Ho3Ge4 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 7-coordinate geometry to three equivalent Ge(2) and four equivalent Ge(3) atoms. In the second Ho site, Ho(2) is bonded in a 8-coordinate geometry to two equivalent Ge(1), two equivalent Ge(2), and four equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 4-coordinate geometry to four equivalent Ho(2) and four equivalent Ge(3) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Ho(1), four equivalent Ho(2), and two equivalent Ge(3) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Ho(1), four equivalent Ho(2), one Ge(2), and two equivalent Ge(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
