Abstract
The article reports the CO2 fixation by Copper(II) complexes of a terpyridinophane Aza Receptor. This is the first reported structure of an abiotic system in which a carbamylation produced by atmospheric CO2 and assisted by a complexed metal ion and by the presence of amino groups in the environment is produced within a macrocyclic structure. Results suggest that carbamate stabilization needs a binding group able to fix spatially the divalent metal ion that assists the process as a Lewis acid and an environment which, at the same time, can acquire positive charge and form a hydrogen-bond network involving the elusive carbamate moiety.
