    Description / Table of Contents: Preparation of CH3SCN · MF5 Adducts (M = As, Sb) and Crystal Structure of CH3SCN · AsF5The preparation and spectroscopic characterization of CH3SCN · MF5 M = As, Sb is reported. X-Ray structure analysis shows that the adduct CH3SCN · AsF5 is N coordinated. It crystallizes in the monoclinic space group P21/m (Nr. 11) with a = 537.07(6) pm, b = 755.28(10) pm, c = 863.19(10) pm, β = 91.81(1)°, Z = 2. The geometric parameters correspond to the expected values.

    Description / Table of Contents: Preparation of Cyanhalogenomethyl and Dicyanhalogensulfonium Salts CH3(CN)SHal+MF6- and (CN)2SHal+MF6- (Hal = F, Cl, Br, I; M = As, Sb) and Methylthionitrilium and (μ-Thio)bisnitriliumhexafluoro Metallates CH3SCNX+MF6- and S(CNH)22+ (MF6-)2 (X = H, D)Oxidative halogenation of CH3SCN and S(CN)2 with XeF+MF6-, Cl2/MF5/SO2, Br2/MF5/SO2 and I3+MF6- leads to S-coordinated cations. The complete spectroscopic series of the halogensulfonium salts CH3S(CN)Hal+MF6- and (CN)2SHal+MF6- (Hal = F, Cl, Br, I; M = As, Sb) as well as hexafluoroarsenate and -antimonate were recorded.However the protonation of divalent cyansulfanes in superacidic media HF/MF5 takes place at the nitrogen atom to nitrilium salts in analogy to the adduct formation with strong Lewis acids.
    Notes: Bei der oxidativen Halogenierung von CH3SCN und S(CN)2 mit XeF+MF6-, Cl2/MF5/SO2, Br2/MF5/SO2 und I3+MF6- erfolgt eine Koordination am Schwefel, und es wurden die kompletten spektroskopischen Reihen der S-Halogensulfoniumsalze CH3S(CN)Hal+MF6- und (CN)2SHal+MF6-(Hal = F, Cl, Br, I; M = As, Sb) jeweils als Hexafluoroarsenat und -antimonat hergestellt.Dagegen erfolgt die Protonierung der divalenten Cyansulfane im supersauren Milieu HF/MF5 am Stickstoff zu Nitriliumsalzen analog wie die Koordination bei der Adduktbildung mit starken Lewissäuren.

    Description / Table of Contents: Redetermination of the Crystal Structure of AsCl4+AsF6-The X-ray crystal structure analysis of AsCl4+AsF6- (P4/n (Nr. 85), a = b = 866.65(15) pm, c = 623.78(17) pm, Z = 2) is reported. Some structural parameters differ largely from values obtained by Weissenberg pictures.

    Description / Table of Contents: Crystal Structure of a new Modification of Sb8F30The modification of Sb8F30, described here, crystallizes in the orthorhombic space group Pca21 (No. 29) with a = 1115.7(1), b = 1100.2(1), c = 1917.8(3) pm and Z = 4. Within this complex molecule, the Sb3F72+-cation was identified besides a heavily distorted form of the mixed valent Sb4F17--anion.

    Description / Table of Contents: Darstellung der Pesudohalogenheptaschwefel(+1)-hexaflourmatellate S7X+MF-6 (X = CN, OCN, SCN, SeCN; M = As, Sb)Es wird über die Darstellung und spektroskopische Charakterisierung von S7X+MF-6 (X = CN, OCN, SCN, SeCN; M = As, Sb) berichtet. Die Verbindungen werden in Analogie zur Darstellung der Halogencycloheptaschwefel(+1)-Kationen aus S2+8(MF-6)2 und Alkalimetallpseudohalogeniden in Schwefeldioxid als Lösungsmittel gebildet. Ihre thermische Stabilität nimmt mit wachsender „Pearson Härte“ der Pseudohalogenliganden ab.
    Notes: The preparation and spectroscopic characterization of S7X+MF-6 (X = CN, OCN, SCN, SeCN; M = As, Sb) is reported. The new compounds are formed in analogy to the preparation of halidocycloheptrasulfur(+1) cations from S2+8(MF-6)2 and alkali pseudohalides in So2 as solvent. Their thermal stabilities decrease with the increasing Pearson hardness of the pseudohalide ligands.
