2-(2,6-Di-Tert-Butyl-4-Methylphenoxy)-2,4,4,6,6,8,8-Heptachlorocyclo-2 Lambda(5),4 Lambda(5),6 Lambda(5),8 Lambda(5)-Tetraphosphazatetraene

Abstract

The title compound, C15H23Cl7N4OP4, consists Of a saddle-shaped cyclic tetrameric phosphazene ring and a bulky 2,6-di-tert-butyl-4-methylphenoxy side group. The bulky group substituent is instrumental in determining the molecular shape. The exo- and endocyclic angles about the P atoms both decrease on substitution whereas the P-N-P angles increase.
