资源简介：
(Trifluoromethyl)iodine dichloride (CF3ICl2) is synthesized by the reaction of (trifluoromethyl)iodine chloride
fluoride (CF3I(Cl)F) with trimethylchlorosilane ((CH3)3SiCl) at −40 °C. By using this route of preparation, in
which CF3I(Cl)F undergoes a chlorine−fluorine exchange, CF3ICl2 can be obtained in high purity and yield.
CF3ICl2 crystallizes in the orthorhombic space group Cmca with a = 6.990(1) Å, b = 7.985(1) Å, c = 21.177(1)
Å, and eight formula units per unit cell. The final R indices [I > 2σ(I)] are R1 = 0.0341 and wR2 = 0.0631.
CF3ICl2 is, in contrast to iodine trichloride (ICl3), monomeric, and its molecular structure is T-shaped with the
CF3 group in the equatorial position. The Raman, IR, and NMR spectra are also described.
