The material described by FeF4 is alpha Po structured and crystallizes in the tetragonal I4/mcm space group. The structure is zero-dimensional and consists of four tetrafluoroiron molecules. Fe(1) is bonded in a square co-planar geometry to four equivalent F(1) atoms. F(1) is bonded in a single-bond geometry to one Fe(1) atom. is represented by the CIF card [CIF]
