The material described by W3Mg is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded to twelve equivalent W(1) atoms to form a mixture of corner and face-sharing MgW12 cuboctahedra. W(1) is bonded in a 4-coordinate geometry to four equivalent Mg(1) atoms. is represented by the CIF card [CIF]
