Acta Crystallographica Section C-crystal Structure Communications | 2004

4,4,6,6-tetrachloro-2,2-(propylene-dioxydi-o-phenylenediimino)-2λ5, 4λ5, 6λ5-cyclo triphosphazene

Baris Tercan; Tuncer Hökelek; Selen Bilge; Bilgehan Özgüç; Zeynel Kılıç

The title compound, C(15)H(16)Cl(4)N(5)O(2)P(3), 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 A.
