Li(PrGe)4 crystallizes in the orthorhombic Pnma space group. Li(1) is bonded in a T-shaped geometry to one Ge(2) and two equivalent Ge(3) atoms. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 7-coordinate geometry to one Ge(2), two equivalent Ge(3), and four equivalent Ge(1) atoms. In the second Pr site, Pr(2) is bonded in a 6-coordinate geometry to one Ge(3), two equivalent Ge(2), and three equivalent Ge(1) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Li(1), two equivalent Pr(2), four equivalent Pr(1), and one Ge(2) atom. In the second Ge site, Ge(1) is bonded in a 8-coordinate geometry to three equivalent Pr(2), four equivalent Pr(1), and one Ge(1) atom. In the third Ge site, Ge(2) is bonded in a 8-coordinate geometry to one Li(1), two equivalent Pr(1), four equivalent Pr(2), and one Ge(3) atom.
