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, a...

Zusammenfassung: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 approximately 1.14 A in radius. The molecules are linked about inversion centres by N-H...N hydrogen bonds into centrosymmetric dimers.
