Nitrido complexes N⋮Mo(OC(CF<sub>3</sub>)<sub>2</sub>Me)<sub>3</sub> (<b>1</b>) and N⋮Mo(OC(CF<sub>3</sub>)<sub>3</sub>)<sub>3</sub>(NCMe) (<b>2</b>) containing fluorinated alkoxide ancillary ligands
are synthesized in 57% and 50% yield, respectively. Both
complexes undergo N-atom exchange within hours at 30 °C with
acetonitrile and benzonitrile in either THF-<i>d</i><sub>8</sub> or CD<sub>2</sub>Cl<sub>2</sub>, as shown
by <sup>15</sup>N NMR studies using labeled <sup>15</sup>NCMe. In both solvents, <b>2</b> is
the more active in this process. Additionally, both compounds are
substantially more active in THF-<i>d</i><sub>8</sub> than in CD<sub>2</sub>Cl<sub>2</sub>. Complex <b>2</b>
crystallizes in the space group <i>P</i>2(1)/<i>c</i>, adopting a pseudo-square-pyramidal structure in which the nitrido moiety occupies the apical
position, 1.633(3) Å away from Mo.
