The crystal structure described by La2IrRh3Ge4 crystallizes in the tetragonal P-4m2 space group. La(1) is bonded in a 16-coordinate geometry to two equivalent Ir(1), two equivalent Rh(1), two equivalent Rh(2), two equivalent Rh(3), four equivalent Ge(1), and four equivalent Ge(2) atoms. Ir(1) is bonded to four equivalent La(1) and four equivalent Ge(1) atoms to form distorted IrLa4Ge4 tetrahedra that share corners with four equivalent Rh(3)La4Ge4 tetrahedra, corners with eight equivalent Rh(1)La4Ge4 tetrahedra, edges with two equivalent Rh(3)La4Ge4 tetrahedra, edges with four equivalent Ir(1)La4Ge4 tetrahedra, and faces with four equivalent Rh(2)La4Ge4 tetrahedra. There are three inequivalent Rh sites. In the first Rh site, Rh(1) is bonded to four equivalent La(1) and four equivalent Ge(2) atoms to form distorted RhLa4Ge4 tetrahedra that share corners with four equivalent Rh(2)La4Ge4 tetrahedra, corners with eight equivalent Ir(1)La4Ge4 tetrahedra, edges with two equivalent Rh(2)La4Ge4 tetrahedra, edges with four equivalent Rh(1)La4Ge4 tetrahedra, and faces with four equivalent Rh(3)La4Ge4 tetrahedra. In the second Rh site, Rh(2) is bonded to four equivalent La(1) and four equivalent Ge(1) atoms to form distorted RhLa4Ge4 tetrahedra that share corners with four equivalent Rh(1)La4Ge4 tetrahedra, corners with eight equivalent Rh(3)La4Ge4 tetrahedra, edges with two equivalent Rh(1)La4Ge4 tetrahedra, edges with four equivalent Rh(2)La4Ge4 tetrahedra, and faces with four equivalent Ir(1)La4Ge4 tetrahedra. In the third Rh site, Rh(3) is bonded to four equivalent La(1) and four equivalent Ge(2) atoms to form distorted RhLa4Ge4 tetrahedra that share corners with four equivalent Ir(1)La4Ge4 tetrahedra, corners with eight equivalent Rh(2)La4Ge4 tetrahedra, edges with two equivalent Ir(1)La4Ge4 tetrahedra, edges with four equivalent Rh(3)La4Ge4 tetrahedra, and faces with four equivalent Rh(1)La4Ge4 tetrahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to four equivalent La(1), two equivalent Ir(1), two equivalent Rh(2), and one Ge(2) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to four equivalent La(1), two equivalent Rh(1), two equivalent Rh(3), and one Ge(1) atom. is represented by the CIF file [CIF]
