Abstract:The title compound, C15H16Cl4N5O2P3, is a cyclophosphazenic lariat (PNP-pivot) ether with a spiro-cyclic 12-membered macrocyclic ligand containing two ether O and two N atoms; the phosphazene ring is nearly planar. In the macrocyclic ring, there is a four-center (trifurcate) N—H…O/N—H…N hydrogen bond. The relative inner-hole size of the macrocycle is estimated as approximately 0.95 Å.
