Materials Data on MgW3 by Materials Project
W3Mg is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Mg is bonded to twelve equivalent W atoms to form a mixture of face and corner-sharing MgW12 cuboctahedra. There are six shorter (2.89 Å) and six longer (2.95 Å) Mg–W bond lengths. W is bonded in a 4-coordinate geometry to four equivalent Mg atoms.
