The reaction of trans-<(PhN)P(NMe2)>2 (1) with 2 equivalents of phenyl azide yields the bis(imino) derivative, trans-<(PhN)P(NMe2)(NPh)>2 (2).The X-ray crystal structure of (2) reveals that the N2P2 ring and the phenyl groups attached to the ring nitrogen atoms are coplanar.The ring nitrogen atoms as well as the nitrogen atoms of the dimethylamino groups display trigonal planar geometry.The bond length of 1.518 Angstroem for the exocyclic P=N bond indicates that this bond is not delocalised with the N2P2 ring system.
