Os3F is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded to four equivalent Os(2) and four equivalent F(1) atoms to form a mixture of distorted corner, edge, and face-sharing OsOs4F4 tetrahedra. In the second Os site, Os(2) is bonded in a body-centered cubic geometry to eight equivalent Os(1) atoms. F(1) is bonded in a body-centered cubic geometry to eight equivalent Os(1) atoms.
