λ3-Cyclodiphosphazanes of the type (RNPX)2 (R=Ph, X=OC6H4-Me-p or OCH2CF3) react with Group 6 metyl carbonyls to yield a variety of complexes depending on the geometrical disposition of the substituents on the phosphorus with respect to the P2N2 ring.Coordination occurs through the phosphorus centre(s) in the ν1- or bridged bidentate(μ-)modes.On the other hand (amino)λ5-cyclotriphosphazenes afford Group 6 metal carbonyl complexes in which a phosphazene ring nitrogen atom is involved in coordination besides exocyclic nitrogen atoms.Complexes of Group 10 metal chlorides with cyclotriphosphazene ligands have also been synthesized.NMR spectroscopic and X-ray crystallographic studies have been carried out to elucidate the structures of the complexes.
