✦ Synopsis

The title compound, C 22 H 15 Cl 4 N 4 O 2 P 3 , 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 ArCH 2 -N), which has a pyramidal geometry, are capable of representing stereogenic centres.
