Abstract
The title compound, C45H55NO6P2, consists of an acyclic P=N-P(O) monophosph azene chain and five bulky 2,4,6-trimethylphenoxy side groups which predomi nantly determine the molecular shape. Although the P-N single [1.586 (3) An gstrom] and P=N double [1.517 (3) Angstrom] bonds are significantly differe nt from each other, both are substantially shorter than the ideal P-N singl e bond. The P-N-P angle [146.0 (2)degrees] corresponds to the upper limit r eported for acyclic phosphazene derivatives in the literature.
