Abstract: The title compound, C₂₂H₁₅Cl₄N₄O₂P₃, is a spiro phosphazene derivative with two bulky naphthalene rings. The phosphazene and the two six-membered N/O rings are not planar. The aliphatic C atom (in ArCH-OAr) and the N atom (in ArCH₂-N), which has a pyramidal geometry, are capable of representing stereogenic centres.
