Molecular Structures of Phosphazenes Determined by -Ray Diffraction Methods

7 Molecular Structures of Phosphazenes Determined by 2T-Ray Diffraction Methods 

Two exo P—N bond lengths of approx. 112 equal length [1.578 and 1.585(7) A], and shorter than nearest endo P—N bond lengths [1.625(7) A] 

Benzene molecules tumbling within channels formed by guest molecules 

Centrosymmetric chair conformation, 115 approx. C2ft symmetry. P—N endo) 

Ring nearly planar with five ring atoms within possible bonding distance. Poor quality crystals gave data of low accuracy
