SiBi3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Si(1) is bonded in a body-centered cubic geometry to eight equivalent Bi(1) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a body-centered cubic geometry to four equivalent Si(1) and four equivalent Bi(2) atoms. In the second Bi site, Bi(2) is bonded in a body-centered cubic geometry to eight equivalent Bi(1) atoms.
