The material structure described by MgTb4Ge4 is Magnesium tetraboride-derived structured and crystallizes in the orthorhombic Pnma space group. Mg(1) is bonded in a 5-coordinate geometry to one Ge(2), two equivalent Ge(1), and two equivalent Ge(3) atoms. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 6-coordinate geometry to one Ge(1), two equivalent Ge(2), and three equivalent Ge(3) atoms. In the second Tb site, Tb(2) is bonded in a 7-coordinate geometry to one Ge(2), two equivalent Ge(1), and four equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), two equivalent Tb(1), four equivalent Tb(2), and one Ge(2) atom. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to one Mg(1), two equivalent Tb(2), four equivalent Tb(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 Tb(1), four equivalent Tb(2), and one Ge(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
