Crystal and molecular structure of the monophenylsulphanuric fluoride trimer (3,5-difluoro-1,3,5-trioxo-1-phenylcyclotriazathiane)

Abstract

An X-ray crystallographic examination of the monophenylsulphanuric fluoride molecule, S₃N₃O₃F₂Ph, shows that the phenyl group is trans to the two fluorine atoms. The crystals of S₃N₃O₃F₂Ph are triclinic, with a= 7·59(2), b= 8·25(3), c= 9·96(3)Å, α= 109·6(1), β= 108·0(2), and γ= 93·3(2)°, space group is P, and Z= 2. The structure has been refined to R 0·12 on the intensities of 1187 reflections collected photographically.
