The material described by MgYb4Ge4 is Magnesium tetraboride-derived structured and crystallizes in the orthorhombic Pnma space group. Mg(1) is bonded in a distorted T-shaped geometry to one Ge(1) and two equivalent Ge(3) atoms. There are two inequivalent Yb sites. In the first Yb site, Yb(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 Yb site, Yb(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(1) is bonded in a 8-coordinate geometry to one Mg(1), two equivalent Yb(2), four equivalent Yb(1), and one Ge(3) atom. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to three equivalent Yb(1), four equivalent Yb(2), and one Ge(2) atom. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Mg(1), two equivalent Yb(1), four equivalent Yb(2), and one Ge(1) atom. is represented by the CIF file [CIF]
