Molybdenum(0) dinitrogen complexes, supported by the mixed NHC/phosphine pincer ligand PCP, exhibit an extreme activation of the N 2 ligand due to a very π‐electron‐rich metal center. The low thermal stability of these compounds can be increased using phosphites instead of phosphines as coligands. Through an amalgam reduction of [MoCl 3 (PCP)] in the presence of trimethyl phosphite and N 2 the highly activated and room‐temperature stable dinitrogen complex [Mo(N 2 )(PCP)(P(OMe) 3 ) 2 ] is obtained. As a second product, the first transition metal complex containing the meta ‐phosphite ligand P(O)(OMe) originates from this reaction.
