The reduction of nitrite (NO2−) to nitric oxide (NO), relevant to the biogeochemical nitrogen cycle as well as radioactive waste, typically occurs at redox-active metal centres. Now, a Lewis acid-capped nitrite has been reduced to the nitrite dianion (NO22−), a nitrogen-centred radical that connects three redox levels in the global nitrogen cycle through NO2−, NO and N2O.
