Özet

The title ligand, C14H14Cl4N5O2P3, is a cyclophosphazene lariat (PNP pivot) ether with a spiro-cyclic 11-membered macrocyclic ring containing two ether O and two N atoms; the phosphazene ring is nearly planar. The macrocyclic ring contains a four-centred (trifurcate) N - H ... O/N - H ... N hydrogen bond, and the relative inner-hole size of the macrocycle is similar to1.14 Angstrom in radius. The molecules are linked about inversion centres by N - H ... N hydrogen bonds into centrosymmetric dimers.
