Carbon dioxide capture from air leading to bis-[N-(5-methyl-1H-pyrazol-3-yl-κN²)carbamato-κO]copper(II) tetra-hydrate.

ABSTRACT: A mononuclear square-planar Cu^II complex of (5-methyl-1H-pyrazol-3-yl)carbamate, [Cu(C₅H₆N₃O₂)₂]·4H₂O, was synthesized using a one-pot reaction from 5-methyl-3-pyrazolamine and copper(II) acetate in water under ambient conditions. The adsorption of carbon dioxide from air was facilitated by the addition of di-ethano-lamine to the reaction mixture. While di-ethano-lamine is not a component of the final product, it plays a pivotal role in the reaction by creating an alkaline environment, thereby enabling the adsorption of atmos-pheric carbon dioxide. The central copper(II) atom is in an (N₂O₂) square-planar coordination environment formed by two N atoms and two O atoms of two equivalent
