The crystal structure described by IF7 is Tungsten structured and crystallizes in the orthorhombic Aea2 space group. The structure is zero-dimensional and consists of four IF7 clusters. I(1) is bonded in a pentagonal bipyramidal geometry to one F(4), two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms. There are four inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to one I(1) atom. In the second F site, F(2) is bonded in a single-bond geometry to one I(1) atom. In the third F site, F(3) is bonded in a single-bond geometry to one I(1) atom. In the fourth F site, F(4) is bonded in a single-bond geometry to one I(1) atom. is represented by the CIF file [CIF]
