Li2Nd2Ge3 crystallizes in the orthorhombic Cmcm space group. Li(1) is bonded to three equivalent Nd(2), one Ge(1), and three equivalent Ge(2) atoms to form a mixture of distorted corner, face, and edge-sharing LiNd3Ge4 tetrahedra. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 9-coordinate geometry to one Ge(2) and eight equivalent Ge(1) atoms. In the second Nd site, Nd(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 Nd(2), four equivalent Nd(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 Nd(1), and two equivalent Nd(2) atoms.
