2-(2,6-Di-tert-butyl-4-methylphenoxy)-2,4,4,6,6,8,8-heptachlorocyclo-2λ⁵,4λ⁵,6λ⁵,8λ⁵-tetraphosphazatetraene

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 determines molecular shape. The exo- and endocyclic angles about the P atoms both decrease, on substitution, whereas the P—N—P angles increase.
