Ge3Sb is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a body-centered cubic geometry to four equivalent Ge(2) and four equivalent Sb(1) atoms. In the second Ge site, Ge(2) is bonded in a body-centered cubic geometry to eight equivalent Ge(1) atoms. Sb(1) is bonded in a body-centered cubic geometry to eight equivalent Ge(1) atoms.
