Observation of Cu2+–H2 Interactions in a Fully Desolvated Sodalite‐Type Metal–Organic Framework

Metal–H2 binding: A new tetrazolate-based metal–organic framework exhibits high H2 uptake at low temperature and moderate pressure. The evacuation of coordinated solvent molecules from Cu2+ ions within the framework provides strong binding sites for H2 molecules (see picture; Cu purple, C gray, N blue, Cl green).
