The title compound, C29H42Cl2N7O2P3, is a phosphazene derivative with a bulky substituent attached through a spiro junction with two pyrrolidine rings. The six-membered C3N2P ring has a chair conformation, while the phosphazene ring has a slight envelope conformation. The two N atoms in the C3N2P ring are likely to be stereogenic.
