Tl3Ga is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a body-centered cubic geometry to four equivalent Tl(2) and four equivalent Ga(1) atoms. In the second Tl site, Tl(2) is bonded in a body-centered cubic geometry to eight equivalent Tl(1) atoms. Ga(1) is bonded in a body-centered cubic geometry to eight equivalent Tl(1) atoms.
