trans-2,4,4,6,8,8-Hexamorpholino-2,6-bis(n-propylamino)cyclo-2lambda5,4lambda5,6lambda5,8lambda5-tetraphosphazatetraene.

Abstract

The title compound, C(30)H(64)N(12)O(6)P(4), consists of a centrosymmetric chair-shaped cyclic tetrameric phosphazene ring with six bulky morpholino and two n-propylamino side groups. The two n-propylamino side groups are in trans positions. The bulky substituents mainly determine 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.
