A new polymorph of 2,2,4,4,6,6-hexaisothiocyanatocyclotriphosphazene

E. Kessenich, A. Schulz and K. Polborn

Abstract: A new polymorph of the title compound, C₆N₉P₃S₆, has been found. In contrast to the already known polymorph, which crystallizes with Z ' = 1 in P, the title structure crystallizes in P2₁/c with Z' = 2.  The two independent molecules in the asymmetric unit show large differences in the ring structure. The non-planarity of the phosphazene ring indicates weak SS interactions of the isothiocyanate groups, as well as packing effects.
