The compound described by MgHo4Ge4 crystallizes in the orthorhombic Pnma space group. Mg(1) is bonded in a 5-coordinate geometry to one Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 7-coordinate geometry to one Ge(1), two equivalent Ge(2), and four equivalent Ge(3) atoms. In the second Ho site, Ho(2) 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 8-coordinate geometry to one Mg(1), two equivalent Ho(1), four equivalent Ho(2), and one Ge(2) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Mg(1), two equivalent Ho(2), four equivalent Ho(1), and one Ge(1) atom. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to one Mg(1), three equivalent Ho(2), four equivalent Ho(1), and one Ge(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
