The material described by F2 is Indium-like structured and crystallizes in the cubic Pm-3n space group. The structure is zero-dimensional and consists of eight hydrofluoric acid atoms. F(1,2) is bonded in a 1-coordinate geometry to  atoms. is represented by the Crystallographic Information File (CIF) [CIF]
