Trifluoromethyl iodine difluoride (CF3IF2) is synthesized by the reaction of trifluoromethyl iodide (CF3I) with trifluoromethyl hypochlorite (CF3OCl) at 223 K. This is a new route of preparation, in which CSI is fluorinated by CF3OCl in an addition-elimination reaction. CF3IF2 crystallizes in the tetragonal space group I (4) over bar 2d with a = 8.509(1) Angstrom, c = 12.324(2) Angstrom, and eight formula units per unit cell. Its molecular structure is T-shaped with a disordered CF3 group. The Raman and IR spectra are described.
