  1. Proton-switchable access to seven-coordinate ONNO dicarboxamide and NNNN dicarboxamidate rhenium oxo complexes provides a platform for understanding thermodynamics and bonding in pentagonal bipyramidal complexes.

  2. Porphyrin complexes are well-known in O 2 and CO 2 reduction, but their application to N 2 reduction is less developed. Here, we show that oxo and nitrido complexes of molybdenum supported by tetramesitylporphyrin (TMP) are effective precatalysts for catalytic N 2 reduction to ammonia, verified by 15 N 2 labeling studies and other control experiments. Spectroscopic and electrochemical studies illuminate some relevant thermodynamic parameters, including the N–H bond dissociation free energy of (TMP)MoNH (43 ± 2 kcal mol −1 ). We place these results in the context of other work on homogeneous N 2 reduction catalysis.
