Li(YGe)4 crystallizes in the orthorhombic Pnma space group. Li(1) is bonded in a distorted T-shaped geometry to one Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 6-coordinate geometry to one Ge(2), two equivalent Ge(1), and three equivalent Ge(3) atoms. In the second Y site, Y(2) is bonded in a 7-coordinate geometry to one Ge(1), two equivalent Ge(2), and four 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 Li(1), two equivalent Y(2), four equivalent Y(1), and one Ge(2) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Li(1), two equivalent Y(1), four equivalent Y(2), and one Ge(1) atom. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to one Li(1), three equivalent Y(1), four equivalent Y(2), and one Ge(3) atom.
