GaSi3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Ga(1) is bonded in a body-centered cubic geometry to eight equivalent Si(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a body-centered cubic geometry to four equivalent Ga(1) and four equivalent Si(2) atoms. In the second Si site, Si(2) is bonded in a body-centered cubic geometry to eight equivalent Si(1) atoms.
