    Description / Table of Contents: Fluorination of Cyanuric Chloride and Low-Temperature Crystal Structure of [(ClCN)3F]+[AsF6]-The low-temperature fluorination of cyanuric chloride, (ClCN)3, with F2/AsF5 in SO2F2 solution yielded the salt [(ClCN)3F]+ [AsF6]- (1) essentially in quantitative yield. Compound 1 was identified by a low-temperature single crystal X-ray structure determination: R 3c, trigonal, a = b = 10.4246(23) Å, c = 15.1850(24) Å, V = 1429.1(4) Å 3, Z = 6, RF = 0.056, Rw = 0.076 (for significant reflections), RF = 0.088, Rw = 0.079 (for all reflections). Fluorination of neat (ClCN)3 with [NF4]+ [Sb2F11]- yielded NF3, CClF3, SbF3, N2 and traces of CF4. A qualitative scale for the oxidizing strength of the oxidative fluorinators NF4+ and (XCN)3F+ (X = H, F, Cl) has been computed ab initio.
    Notes: Durch Tieftemperaturfluorierung von Cyanurchlorid, (ClCN)3, mit F2/AsF5 in SO2F2-Lösung wurde [(ClCN)3F]+ [AsF6]- (1) in nahezu quantitativer Ausbeute dargestellt, aus SO2 bei Raumtemperatur umkristallisert und durch eine Tieftemperatur-Röntgenstrukturanalyse (-170°C) identifiziert: R 3c, trigonal, a = b = 10,4246(23) Å, c = 5,1850(24) Å, V = 1 429,1(4) Å3, Z = 6, RF = 0,056, Rw = 0,076 (für wesentliche Reflexionen), RF = 0,088, Rw = 0,079 (für alle Reflexe). Die Fluorierung von festem (ClCN)3 mit [NF4]+ [Sb2F11]- im Molverhältnis 1:2 lieferte NF3, CClF3, SbF3, N2 und Spuren an CF4. Eine qualitative Reihenfolge bezüglich der FPDE-Werte von NF4+ und (XCN)3F+ (X = H, F, Cl) wurde ab initio berechnet.
