The crystal structure described by La2Mn3CuGe4 crystallizes in the tetragonal P-4m2 space group. La(1) is bonded in a 16-coordinate geometry to two equivalent Mn(1), two equivalent Mn(2), two equivalent Mn(3), two equivalent Cu(1), four equivalent Ge(1), and four equivalent Ge(2) atoms. There are three inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to four equivalent La(1) and four equivalent Ge(2) atoms to form MnLa4Ge4 tetrahedra that share corners with eight equivalent Cu(1)La4Mn4Ge4 cuboctahedra, corners with four equivalent Mn(2)La4Cu4Ge4 tetrahedra, edges with two equivalent Mn(2)La4Cu4Ge4 tetrahedra, edges with four equivalent Mn(1)La4Ge4 tetrahedra, and faces with four equivalent Mn(3)La4Ge4 tetrahedra. In the second Mn site, Mn(2) is bonded to four equivalent La(1), four equivalent Cu(1), and four equivalent Ge(1) atoms to form distorted MnLa4Cu4Ge4 tetrahedra that share corners with four equivalent Mn(2)La4Cu4Ge4 tetrahedra, corners with four equivalent Mn(1)La4Ge4 tetrahedra, corners with eight equivalent Mn(3)La4Ge4 tetrahedra, edges with two equivalent Mn(1)La4Ge4 tetrahedra, faces with four equivalent Cu(1)La4Mn4Ge4 cuboctahedra, and faces with four equivalent Mn(2)La4Cu4Ge4 tetrahedra.
