Synthesis of the Dichloromethyleneiminium Salts Cl2C=NClH+MF6- and Cl2C=NClCH3+ MF6- (M = As, Sb) and Crystal Structure of Dichloromethyleneiminium-hyxachloroantimonate Cl2C=NH2+SbCl6-The N-chloro-dichloromethyleneiminium salts Cl2C=NCIH+MF6- (M = As, Sb) are prepared by protonationof trichloromethyleneimine in the superacide system HF/MF5 at 195 K. The synthesis of the N-chloro-N-methyl-dichloromethyleneiminium salts Cl2C=NClCH3+MF6- (M = As, Sb) is proceeded by methylation of perchloromethylenimine by CH3OSO+MF6- in SO2 also at low temperature. All salts are characterized by vibrational and NMR spectra. The dichloromethyleneiminiumhexachloroantimonate crystallizes in the space group P21/c with a = 971.3(4)pm, b = 1134.0(4)pm, c = 2154.2(7)pm β = 102.04(3)° and Z = 8.
Notes:
Die N-Chlor-dichlormethyleniminium-Salze Cl2C=NClH+MF6- (M = As, Sb) werden aus Trichlormethylenimin durch Protonierung mit dem supersauren System HF/MF5 bei 195 K dargestellt. Die Synthese der N-Chlor-N-methyl-dichlormethylen-iminium-Salze Cl2C=NClCH3+MF6- (M = As, Sb) erfolgt durch Methylierung von Perchlormethylenimin mit CH3OSO+MF6- in SO2 ebenfalls bei tiefer Temperatur. Alle Salze werden schwingungs- und NMR-spektroskopisch charakterisiert. Dichlormethyleniminiumhexachloroantimonat kristallisiert monoklin in der Raumgruppe P21/c mit a = 971,3(4)pm, b = 1134,0(4)pm, c = 2154,2(7) pm, β = 102,04(3)° und Z = 8.
