Li2Pr2Ge3 crystallizes in the orthorhombic Cmcm space group. Li(1) is bonded to three equivalent Pr(2), one Ge(1), and three equivalent Ge(2) atoms to form a mixture of distorted face, corner, and edge-sharing LiPr3Ge4 tetrahedra. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 9-coordinate geometry to one Ge(2) and eight equivalent Ge(1) atoms. In the second Pr site, Pr(2) is bonded in a 12-coordinate geometry to six equivalent Li(1), two equivalent Ge(2), and four equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to one Li(1), two equivalent Pr(2), four equivalent Pr(1), and two equivalent Ge(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to six equivalent Li(1), one Pr(1), and two equivalent Pr(2) atoms.

Li(1) is bonded to three equivalent Pr(2), one Ge(1), and three equivalent Ge(2) atoms to form a mixture of distorted face, corner, and edge-sharing LiPr3Ge4 tetrahedra. There is one shorter (3.13 Å) and two longer (3.17 Å) Li(1)-Pr(2) bond lengths. The Li(1)-Ge(1) bond length is 2.59 Å. There are two shorter (2.65 Å) and one longer (2.75 Å) Li(1)-Ge(2) bond length. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 9-coordinate geometry to one Ge(2) and eight equivalent Ge(1) atoms. The Pr(1)-Ge(2) bond length is 3.15 Å. There are four shorter (3.15 Å) and four longer (3.34 Å) Pr(1)-Ge(1) bond lengths. In the second Pr site, Pr(2) is bonded in a 12-coordinate geometry to six equivalent Li(1), two equivalent Ge(2), and four equivalent Ge(1) atoms. Both Pr(2)-Ge(2) bond lengths are 3.20 Å.
