The crystal structure described by Li2Cu3Ge is Hexagonal Laves-derived structured and crystallizes in the trigonal R-3m space group. Li(1) is bonded in a 12-coordinate geometry to nine equivalent Cu(1) and three equivalent Ge(1) atoms. Cu(1) is bonded to six equivalent Li(1), four equivalent Cu(1), and two equivalent Ge(1) atoms to form CuLi6Cu4Ge2 cuboctahedra that share corners with four equivalent Ge(1)Li6Cu6 cuboctahedra, corners with fourteen equivalent Cu(1)Li6Cu4Ge2 cuboctahedra, edges with six equivalent Cu(1)Li6Cu4Ge2 cuboctahedra, faces with six equivalent Ge(1)Li6Cu6 cuboctahedra, and faces with twelve equivalent Cu(1)Li6Cu4Ge2 cuboctahedra. Ge(1) is bonded to six equivalent Li(1) and six equivalent Cu(1) atoms to form GeLi6Cu6 cuboctahedra that share corners with six equivalent Ge(1)Li6Cu6 cuboctahedra, corners with twelve equivalent Cu(1)Li6Cu4Ge2 cuboctahedra, edges with six equivalent Ge(1)Li6Cu6 cuboctahedra, and faces with eighteen equivalent Cu(1)Li6Cu4Ge2 cuboctahedra. is represented by the CIF file [CIF]
