The structure described by BeLaCu12 crystallizes in the cubic Fm-3c space group. Be(1) is bonded in a cuboctahedral geometry to twelve equivalent Cu(1) atoms. La(1) is bonded in a 24-coordinate geometry to twenty-four equivalent Cu(1) atoms. Cu(1) is bonded in a 12-coordinate geometry to one Be(1), two equivalent La(1), and nine equivalent Cu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
