The title spirocyclic compound (alternative name: 2,2,4,4‐tetrachloro‐9,9‐dimethyl‐7,11‐dioxa‐1,3,5‐triaza‐2λ5,4λ5,6λ5‐triphosphaspiro5.5undeca‐1,3,5‐triene), C5H10Cl4N3O2P3, does not contain alternating long–short P—N bond lengths in the phosphazene ring P—N 1.559 (2)–1.596 (2) Å, as are observed in other analogous spirocyclic compounds. The six‐membered phosphazene ring has a chair conformation in the solid state, but a conformational equilibrium in solution is indicated by NMR spectroscopy.
