Description
The title ligand, C30H46N9O2P3, is a cyclophosphazenic lariat (PNP pivot) ether with a spiro-cyclic 11-membered macrocyclic ring, containing two N and two ether O atoms, and four pyrrolidino rings; the phosphazene ring is not planar. It belongs to the space group P21/n with cell parameters a = 9.2134(8), b = 9.826(3), c = 36.150(4)Å and β = 90.097(9)°. The macrocyclic ring contains a three-centered (bifurcate) N-H…O hydrogen bond, and the relative inner-hole size (radius) of the macroring is ∼1.16 Å.
