The structure described by MgLu4Ge4 crystallizes in the orthorhombic Pnma space group. Mg(1) is bonded to one Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms to form distorted corner-sharing MgGe5 square pyramids. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 6-coordinate geometry to one Ge(3), two equivalent Ge(1), and three equivalent Ge(2) atoms. In the second Lu site, Lu(2) is bonded in a 7-coordinate geometry to one Ge(1), two equivalent Ge(3), and four equivalent Ge(2) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Mg(1), two equivalent Lu(1), four equivalent Lu(2), and one Ge(1) atom. In the second Ge site, Ge(1) is bonded in a 8-coordinate geometry to one Mg(1), two equivalent Lu(2), four equivalent Lu(1), and one Ge(3) atom. In the third Ge site, Ge(2) is bonded in a 9-coordinate geometry to one Mg(1), three equivalent Lu(1), four equivalent Lu(2), and one Ge(2) atom. is represented by the CIF card [CIF]
