The structure described by Li2Sm2Ge3 crystallizes in the orthorhombic Cmcm space group. Li(1) is bonded to three equivalent Sm(2), one Ge(1), and three equivalent Ge(2) atoms to form a mixture of distorted face, corner, and edge-sharing LiSm3Ge4 tetrahedra. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 9-coordinate geometry to one Ge(2) and eight equivalent Ge(1) atoms. In the second Sm site, Sm(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 Sm(2), four equivalent Sm(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 Sm(1), and two equivalent Sm(2) atoms. is represented by the CIF file [CIF]
