MgY3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Mg(1) is bonded in a body-centered cubic geometry to six equivalent Y(1) and eight equivalent Y(2) atoms. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a distorted body-centered cubic geometry to six equivalent Mg(1) and eight equivalent Y(2) atoms. In the second Y site, Y(2) is bonded in a distorted body-centered cubic geometry to four equivalent Mg(1) and four equivalent Y(1) atoms.
