The title compound, C15H23Cl5N3OP3, consists of a non-planar trimeric phosphazene ring and a bulky 2,6-di-tert-butyl-4-methylphenoxy side group in which the phenyl ring shows a small but significant distortion from planarity. The bulky group predominantly determines the molecular shape. The endocyclic angle about the P atom bonded to the substituent is decreased, while the exocyclic angle is increased. The situation is not similar to that of tetrameric phosphazene derivatives.
