Crystal chemical analysis was carried out of compounds containing UO22+ ions in the structure, which coordinate fluorine and oxygen atoms. It was found that in 193 complexes of the composition UObFc at b ≥ 2 and c ≠ 0, the U(VI) atoms exhibit coordination numbers of 7 and 8. The volume of the Voronoi–Dirichlet polyhedra of U(VI) atoms in the UObFc complexes was found to regularly reduce with increasing parameter λ = c/(b + c). The data on the most important topological features of structural groups arising from the mutual binding of UObFc complexes are systematized. It was established that formed by UO2F5 pentagonal bipyramids, which are connected to each other only by common equatorial vertices or edges, can have an identical topology even at different F : U ratios.
