An unprecedented genre of lanthanide-based coordination polymers to widen the scope of CO2 fixation

Abstract

Trivalent lanthanide ions (Ln(III)) in conjunction with various Schiff base ligands have long been used for fixing CO₂ into inorganic carbonate. However, the responsible reactive species in this regard remained unknown until now. We reveal herein an unprecedented genre of Ln(III)-based coordination polymers that were found to be the reactive species for the formation of inorganic carbonate and can result in organic orthocarbonate upon capturing CO₂.
