Fig. 5: Crystal structure of Co-TG in CO₂-adsorbed state.

a View from the same as Fig. 4d. b Overlayed image of the fragments in the bilayer motif of the Co-TG framework, containing two crystallographic asymmetric units, with hydrogen atoms omitted. Green and yellow atoms correspond to the desolvated and CO₂-adsorbed states, respectively. c The 1D corrugated pore and CO₂ molecules accommodated in the 0D-like cavity. d Perspective view of the array of the 1D corrugated channels and the CO₂ molecules accommodated in the 0D-like cavity. e Two configuration models of a CO₂ molecule disordering in one of the 0D-like cavities with the surrounding atoms of the TG framework.
