The synthesis and characterisation of Pt⁰, Pt^II, Pd^II, Rh^I, and W⁰ complexes containing the RP(NR')P=CR'(R=Et3C, R'=t-Bu) ring system are reported, and their NMR spectroscopic data are discussed.Low oxidation state metal fragments bond through the two-coordinate phosphorus, whereas the three-coordinate phosphorus atom is the donor towards Pd^II and Pt^II.Both phosphorus atoms are ligated in a dinuclear Pt^II complex.
