Acta Crystallogr C. 2001 Oct;57(Pt 10):1228-30. doi: 10.1107/s010827010101441x. Epub 2001 Oct 12.

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.
