The crystal structure described by IF3 is High Pressure (4-7GPa) Tellurium structured and crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four IF3 clusters. I(1) is bonded in a T-shaped geometry to one F(1) and two equivalent F(2) atoms. There are two inequivalent F sites. In the first F site, F(2) is bonded in a single-bond geometry to one I(1) atom. In the second F site, F(1) is bonded in a single-bond geometry to one I(1) atom. is represented by the CIF card [CIF]
