Chemistry freshmen learn to distinguish between nitrate NO3− and nitrite NO2− or sulfate SO42− and sulfite SO32−, but how many would know about carbonite CO22−in contrast to carbonate CO32−? This is not surprising for an anion that has never been observed in solution. However, it might be a crucial intermediate in the reductive activation of CO2. This review will track back carbonite and reflect on its relevance to carbon dioxide binding in metal complexes.
