The material structure described by Ho3(FeGe)4 crystallizes in the orthorhombic Immm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 12-coordinate geometry to six equivalent Fe(1), two equivalent Ge(1), and four equivalent Ge(2) atoms. In the second Ho site, Ho(2) is bonded to two equivalent Ge(1) and four equivalent Ge(2) atoms to form distorted edge-sharing HoGe6 octahedra. Fe(1) is bonded in a 8-coordinate geometry to three equivalent Ho(1), one Fe(1), one Ge(2), and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to one Ho(2), two equivalent Ho(1), and six equivalent Fe(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Ho(2), four equivalent Ho(1), two equivalent Fe(1), and one Ge(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
