Abstract

A novel amino-decorated NbO-type metal–organic framework [Cu₂(C₂₂H₁₁NO₈)(H₂O)₂]·(DMF)₆·(H₂O), (ZJU-8, ZJU = Zhejiang University; DMF = N,N-dimethylformamide) has been synthesized and structurally characterized. The activated ZJU-8a exhibits both a high C₂H₂ uptake capacity (195 cm³ g⁻¹ at 1 bar) and a moderately high adsorption selectivity for CO₂ over N₂ (12.27) and CH₄ (7.38) at room temperature.
