Özet

The title compound, C28H60N12O6P4, consists Of a chair-shaped cyclic tetrameric phosphazene ring with six bulky morpholino and two ethylamino side groups. The two ethylamino side groups are in trans positions. The bulky substituents are effective in determining the eight-membered-ring conformation. The endocyclic N-P-N angles around the P atoms having different substituents are not the same as the P-N-P angles of the macrocyclic ring.
