MgBe4Cu is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Mg(1) is bonded in a 16-coordinate geometry to twelve equivalent Be(1) and four equivalent Cu(1) atoms. Be(1) is bonded to three equivalent Mg(1), six equivalent Be(1), and three equivalent Cu(1) atoms to form a mixture of face, corner, and edge-sharing BeMg3Be6Cu3 cuboctahedra. Cu(1) is bonded in a 16-coordinate geometry to four equivalent Mg(1) and twelve equivalent Be(1) atoms.
