Rapid nitrite reduction enabled by secondary sphere hydrogen bonds within non-heme iron complexes

A non-heme iron( ii ) complex bearing a ligand with secondary sphere hydrogen bond donors, (tris(6-phenylaminopyridylmethyl))amine, rapidly reduces nitrite to nitric oxide in the absence of exogenous additives, affording a Fe( iii ) 2 (μ-O) 2 diamond core.
