The compound described by UOF4 crystallizes in the tetragonal I-42d space group. U(1) is bonded to one O(1), two equivalent F(1), and four equivalent F(2) atoms to form distorted corner-sharing UOF6 pentagonal bipyramids. O(1) is bonded in a single-bond geometry to one U(1) atom. There are two inequivalent F sites. In the first F site, F(2) is bonded in a distorted linear geometry to two equivalent U(1) atoms. In the second F site, F(1) is bonded in a single-bond geometry to one U(1) atom. is represented by the CIF file [CIF]
