The reactions of the bicyclic 1,3,2-λ3,4-λ3-diazadiphosphetidines (PhNP)2(XCH2CH2Y) (X = Y = O (1); X = O, Y = NMe (2)) with Group 6 metal carbonyl derivatives give the mononuclear complexes M(CO)4L2 and M(CO)3L3 in which the cyclodiphosphazane ligand (L) exhibits η1-mode of coordination through one of its phosphorus atoms.Reactions of 1 with M2Cl4(PEt3)2 (M = Pd or Pt) yield both mononuclear and dinuclear complexes.MCl2(PEt3) (1) and M2Cl4(PEt3)2 (1) in which the cyclodiphosphazane ligand is bound to the metal in monodentate and bridged bidentate fashion, respectively.Treatment of 1 with PdCl2(COD) gives a complex of composition n in which the cyclodiphosphazane functions as a bridging bidentate ligand.Structures of the compounds have been elucidated by 1H and 31P NMR spectroscopic studies.
