Molybdenum and tungsten bis(dinitrogen) complexes of the formula M(N 2) 2(PNP) 2 (M = Mo and W) and W(N 2) 2(dppe)(PNP), supported by diphosphine ligands containing a pendant amine of the formula (CH 2PR 2) 2NR′ = P RN R′P R (R = Et, Ph; R′ = Me, Bn), have been prepared by Mg reduction of metal halides under an N 2 atmosphere. The complexes have been characterized by NMR and IR spectroscopy, X-ray crystallography, and cyclic voltammetry. Reactivity of the target Mo and W bis(dinitrogen) compounds with CO results in the formation of dicarbonyl complexes.
