摘要：

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 (CH2PR2)(2)NR' = (PNPR)-N-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.
