Chemical reduction of 6 results in N–N bond cleavage to generate a cis/trans mixture of the [Ta­(V),Ta­(V)] bis­(μ-nitrido) product 7 in tetrahydrofuran and the mononuclear Ta­(V) parent imide 8 in toluene. These results serve to establish an important foundation for the pursuit of a group-5 metal variant of the Schrock cycle for dinitrogen fixation. %I ACS Publications
