The crystal structure described by MgBe3 crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded in a 12-coordinate geometry to twelve equivalent Be(1) atoms. Be(1) is bonded in a 10-coordinate geometry to four equivalent Mg(1) and six equivalent Be(1) atoms. is represented by the CIF file [CIF]
