    Description / Table of Contents: Crystal and Molecular Structure of S3N5PF2The structure of the title compound has been determined from three-dimensional X-ray data, by PATTERSON and FOURIER methods. Crystals are hexagonal, with unit cell dimensions a = 18.9l0, c = 5.302 A, space group R3m C3v5, and Z = 9. Least squares refinement, by use of 499 independent reflections measured on a diffractometer has reached R 4.3%.The structure is built of discrete SSN5PF2 molecules which can be looked upon as S4N4derivative: two opposite sulfur atoms are N-bridged and a third is substituted for a PF2-group. Contrary to a previously proposed structure1 the enviroment of phosphorus is tetrahedral. The now reported structure is in excellent agreement with chemical properties, mass-spectroscopie, and ESR-data.
    Notes: Die Struktur von S3N5PF3 wurde röntgenographisch bestimmt. Die Verbindung kristallisiert hexagonal in der Raumgruppe R3m-C3v5 mit a = 18,910, c = 5,302 Å und Z = 9. Die Verfeinerung nach der Methode der kleinsten Quadrate ergab einen R-Wert von 4,3%. Die Struktur der Molekel kann man sich abgeleitet denken vom S4N4 durch Verbrückung zweier sich gegenüberliegender Schwefelatome durch ein Stickstoff-Atom und Ersatz eines weiteren Schwefelatome durch eine PF2-Gruppe. Phosphor ist tetraedrisch koordiniert. Die gefundene Struktur steht in bester Übereinstimmung mit den chemischen Eigenschaften und den ESR- und massenspektroskopischen Befunden.
