    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.
    Notes: Es wird über die Kristallstruktur von AsCl4+AsF6- (P4/n (Nr. 85) a = b = 866,65(15) pm, c = 623,78(17) pm, Z = 2) berichtet. Einige Strukturparameter unterscheiden sich erheblich von früheren aus Weissenberg-Aufnahmen bestimmten Werten.

    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.
