Table 2.

Yields of NH₃ and N₂H₄ (per equivalent of iron complex) after treatment of crude reaction mixtures containing 1-K₂ or 7-K₃ with 20 equiv of acid. The yields given in bold are an average of multiple runs and the errors correspond to the range of observed values (see Table S2); all other entries are for a single run.
