The synthesis of TAS+ C3N3F4- (1) (TAS+ = (Me2N)3S+) and the reactions of 1 with Me3SiOSiMe3 and Me3SiCF3 to give TAS+ C3N3F2O- (2) and TAS+[(NCF)(NCCF3)(NC(CF3)(2)]- (4) are reported. An isomer of 4, TAS+[(NCCF3)2(NCFCF3)]-, compound 6, was obtained by fluoride ion addition to (CF3CN)3. From the reactions with Me3SiNMe2 neutral fluoroamino triazines C3N3Fn(NMe2)(n-1) (n = 1, 2) were isolated. Possible reaction pathways are discussed, the X-ray structures of 1, 2, 4 and 6 were determined.

TAS ϩ [P 4 N 4 F 8 NMe 2 ] Ϫ (2) was prepared from TAS ϩ [P 4 N 4 F 9 ] Ϫ (1) via F/NMe 2 exchange using Me 3 SiNMe 2 . The salt was characterised by nmr-spectroscopy and by X-ray crystallography. The bonding situation in the anion is briefly discussed. 1673The structural properties of the anion are compared with those of the starting material.

the fluorooxophosphazenate anion of title, crystallizes in the monoclinic space group P21/n with Z = 4 (single crystal XRD). Similar to N4P4F8, the anion N4P4F7Oadopts a saddle conformation with the four phosphorus centers forming a plane. -(KINGSTON, M.; LORK, E.; MEWS*, R.; J. Fluorine Chem. 125 (2004) 5, 681-684; Inst.

the First Chloro Imino-and Chloro Bis(imino)sulfinates. -As revealed by single crystal XRD compound (III) crystallizes in the monoclinic space group P21/c with Z = 4 and compound (V) in the monoclinic space group P21/c with Z = 2. The compounds represent the first chloro imino-and chloro bis(imino) sulfinates, respectively. -(KINGSTON, M.; LORK, E.; VIETS, D.; WATSON, P. G.; MEWS*, R.; J.
