Crystal structure of 2,2,4,4,6-pentafluoro-6-[N-(l,2,4,3,5-trithiadiazol-1-ylidene)amino]cyclotriphosphazene, S3N2NP3N3F5

Abstract

Crystals of the title compound are orthorhombic, space group Pbca with a= 15.915(3), b= 14.641(3), c= 6.700(3)Å, and Z= 8. The structure was solved from diffractometer data using direct methods and refined by least-squares to R= 0.037 for 1 528 observed reflections. The molecule consists of a cyclotriphosphazene ring bonded through a bridging nitrogen atom to a five-membered S₃N₂ ring.
