Abstract

PCM-14 is a dense coordination polymer formed from Ca(II) and an unusual organophosphonium ligand. The dehydrated framework contains 3-coordinate Ca(II) sites within catenated, chiral 3,3-connected nets. PCM-14 exhibits a stark CO₂ sorption selectivity over H₂, N₂ and O₂. The maximum CO₂ uptake was shown to be highly sensitive to the material pretreatment evacuation temperature.
