The material structure described by LaCoCu12 crystallizes in the cubic Fm-3c space group. La(1) is bonded in a 24-coordinate geometry to twenty-four equivalent Cu(1) atoms. Co(1) is bonded to twelve equivalent Cu(1) atoms to form CoCu12 cuboctahedra that share corners with twelve equivalent Cu(1)La2CoCu9 cuboctahedra and faces with twenty-four equivalent Cu(1)La2CoCu9 cuboctahedra. Cu(1) is bonded to two equivalent La(1), one Co(1), and nine equivalent Cu(1) atoms to form distorted CuLa2CoCu9 cuboctahedra that share  a cornercorner with one Co(1)Cu12 cuboctahedra, corners with twenty-seven equivalent Cu(1)La2CoCu9 cuboctahedra, edges with eight equivalent Cu(1)La2CoCu9 cuboctahedra, faces with two equivalent Co(1)Cu12 cuboctahedra, and faces with twenty-three equivalent Cu(1)La2CoCu9 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
