    Description / Table of Contents: Preparation of N-Methyl-N-chlornitryl Hexafluoro Metallates ON(Cl)CH3+MF6- (M = As, Sb).The preparation of ON(Cl)CH3+MF6- (M = As, Sb) by methylation of ONCl with CH3OSO+MF6- (M = As, Sb) is reported. Both salts were unlimited stable at - 78°C. The nitryl cation which is isoelectronic with acetyl chloride was identified by vibrational spectroscopy as N-chloro-N-hydroxy-methaneiminium cation in the solid state.
    Notes: Die Darstellung der N-Methyl-N-chlornitryl-hexafluorometallate ON(Cl)CH3+MF6- (M = As, Sb) erfolgt durch Methylierung von ONCl mit CH3OSO+MF6-. Beide Salze sind unterhalb von - 78°C unbegrenzt haltbar. Das mit Acetylchlorid isoelektronische Nitrylkation erfährt im Festkörper nach schwingungsspektroskopischen Untersuchungen eine Tautomerie zu einem N-Chlor-N-hydroxo-methaniminium-Kation.

    Description / Table of Contents: Gas Phase Structure of CF3NCl2 and Preparation of CF3NCl2F+MF6- (M = As, Sb) and CF2 = NCl2F+SbF6-The gas phase structure of CF3NCl2 is reported. The following skeletal parameters are derived (ra-values, error limits are 3σ values): N—C = 1.470(6) Å, N—Cl = 1.733(3) Å, ClNCl = 111.5(4)° and ClNC = 107.6(5)°. CF3NCl2F+MF6- is prepared by fluorination of CF3NCl2 with XeF+MF6-. The same educt CF3NCl2 reacts with XeF+SbF6- at -40°C to CF2 = NClF+SbF6- under elimination of ClF.
    Notes: Es wird über die Gasphasenstruktur von CF3NCl2 berichtet. Der N—C-Bindungsabstand (ra-Wert, Fehlergrenze 3σ-Wert) beträgt 1,470(6) Å, der N—Cl-Abstand 1,733(3) Å und die Bindungswinkel am Stickstoff ClNCl = 111,5(4)° und ClNC = 107,6(5)°.Durch Fluorierung des Amins mit XeF+MF6- (M = As, Sb) können die bis -50°C stabilen Fluorammoniumsalze CF3NCl2F+MF6- synthetisiert werden. Mit dem gleichen Edukt CF3NCl2 reagiert XeF+SbF6- bei -40°C unter ClF-Abspaltung zu CF2 = NClF+SbF6-.

    Description / Table of Contents: The Gas Phase Structures of CF3NBr2 and (CF3)2NBrThe gas phase structures of the trifluoromethyl bromoamines CF3NBr2 and (CF3)2NBr were determined by electron diffraction. CF3NBr2: N—Br = 188.0(3), N—C = 148.1(13) pm, BrNBr = 111.1(6)° and BrNC = 107.3(8)°; (CF3)2NBr: N—Br = 186.9(4), N—C = 144.9(7) pm, BrNC = 114.9(9)° and CNC = 118.6(24)°. The results for these bromoamines are compared to those for the analogous fluoro and chloroamines.
