    Description / Table of Contents: In addition to the formation of S4N4, greenish-yellow crystal sheets of S3N2F2 are deposited from a mixture containing SN2F2 and SNF at pressures form 600 to 700 mm Hg. S3N2F2 crystallizes in two polymorphic forms; the melting and decomposition points are 85 and 95 - 97° Cm, respectively; solubility in CCl4 at 20°C: 1.5 grs./100 grs. The observed formation of S3N2F2 is discussed in respect to the tendency of stable S—F-bond formation.
    Notes: Aus einem Gemisch von SN2F2 und SNF scheidet sich bei Drucken von 600 bis 700 Torr an der Wand des Reaktionskolbens ein gelber Beschlag ab, während gleichzeitig grüngelbe Kristallblättchen ins Innere des Kolbens wachsen. Bei letzteren handelt es sich um S3N2F2, das in zwei polymorphen Kristallarten auftritt. Fp. 85°C; Zers.-Pkt. 95-97°C. Löslichkeit in CCl4: 1,5 g/100 g bei 20°.Aus dem gelben Wandbeschlag wird durch Dekantieren mit Acetonitril S4N4 erhalten. Die Bildung von S3N2F2 wird diskutiert und festgestellt, daß die Tendenz zur Bildung stabiler S—F-Bindungen als Ursache für die Zersetzung von SN2F2 + SNF angesehen werden kann.
