Reaction of Chlorine Nitrate with CF3I: Isolation of Trifluormethylchloroiodinenitrate CF3I(Cl)ONO2 and the Crystal Structure of Trifluormethyliodinedinitrate CF3I(ONO2)2CF3I reacts with ClONO2 to Iodine(III)-compounds. After an addition CF3I(Cl)ONO2 is isolated and characterized by vibrational spectra. With surplus ClONO2 it is formed CF3I(ONO2)2.CF3I(ONO2)2 crystallizes monoclinic in the space group P21/c with the cell parameters a = 1 024.3(6) pm, b = 873.5(6) pm, c = 873.4(6) pm and Z = 4.We measered following bonding distances: I—O: 207.3(3) and 220.8(2) pm, I—C: 221.1(4) pm and N—O: from 119.1(4) to 141.5(3) pm.Through an intermolecular I ··· O-contact the central iodine becomes a distorted plane geometry.
Notes:
CF3I reagiert mit ClONO2 in einer oxidativen Additionsreaktion zu Iod(III)-Verbindungen. Das Additionsprodukt CF3I(Cl)ONO2 wird isoliert und schwingungsspektroskopisch charaktersiert. Mit überschüssigem ClONO2 bildet sich CF3I(ONO2)2.CF3I(ONO2)2 kristallisiert monoklin in der Raumgruppe P21/c mit a = 1 024,3(6) pm, b = 873,5(6) pm, c = 873,4(6) pm und Z = 4.Es werden folgende Bindungslängen gemessen: I—O: 207,3(3) bzw. 220,8(2) pm, I—C: 221,2(4) pm und N—O: 119,1(4) bis 141,5(3) pm.Durch einen intermolekularen I ··· O-Kontakt erlangt das zentrale Iodatom eine verzerrt-planare Umgebung.
