    Notes: The molecular structure of (CF3)2NOCH3 was determined by gas electron diffraction. The molecular intensities were reproduced by use of a single conformation with syn orientation of the O-CH3 group relative to the nitrogen lone pair. This was confirmed by ab initio calculations (HF/3-21G(*), polarization functions only on nitrogen, and MP2/6-31G*). The observed structure demonstrates that the generalized anomeric effect is of minor importance to this compound. The following skeletal geometric parameters (bond lengths [pm] and angles [°] with 3-s̰ uncertainties) were derived: N-C 142.9(7), N-O 142(3), O-C 145(3), CNC 118.0(9), CNO 108.1(17), and NOC 109.4(17). The experimental structure is well reproduced by the ab initio calculations.

    Description / Table of Contents: New N,N-Dichloromethylsulfonammonium Salts CH3S(O)2NCl2X+MF6- (X = CH3, Cl, F; M = As, Sb) and Crystal Structure of CH3S(O)2NCl2The preparations of new dichlorammonium salts CH3S(O)2NCl2X+MF6- (X = CH3, Cl, F; M = As, Sb) and of CH3S(O)2NCl2 by oxidative halogenation respectively methylation are reported. The thermolabil compounds are characterized by IR, Raman, 1H, 13C, 19F NMR spectroscopy. N,N-Dichlormethylsulfonamid CH3S(O)2NCl2 crystallizes at 173(1) K in the orthorhombic space group Pnma with a = 615.1(3) pm, b = 937.3(5) pm, c = 970.3(5) pm and Z = 4.
    Notes: Die Darstellung einer Reihe von Dichlor ammoniumsalzen des Typs CH3S(O)2NCl2X+MF6- (X = CH3, Cl, F; M = As, Sb) wird angegeben. Die Salze werden durch oxidative Halogenierung bzw. Methylierung von CH3S(O)2NCl2 erhalten. Die Charakterisierung der thermolabilen Verbindungen erfolgte mittels IR-, Raman-sowie Multikern-NMR-Spektroskopie. Die Einkristallröntgenstrukturanalyse von N,N-Dichlormethylsulfonamid CH3S(O)2NCl2 bei 173(1) K ergab: orthorhombische Raum gruppe Pnma mit a = 615,1(3) pm, b = 937,3(5) pm, c = 970,3(5) pm und Z = 4.
