An insight into the route from the fixation of CO₂ gas into CO₃^2- and the concomitant formation of a novel series of carbonato-bridged dinuclear lanthanide(III) complexes is presented. Efficient and quantitative conversion of CO₂ gas into CO₃^2- is confirmed by deliberately employing CO₂ gas as a reagent. The feature of inner coordination post-synthetic modification is demonstrated via ligand substitution at the terminally axial coordination sites of the dinuclear motifs. Spectroscopic and X-ray crystallographic techniques were employed for probing the reactions and structural elucidation of the products.
