Hydrogen Uptake by an Inclined Polycatenated Dynamic Metal–Organic Framework Based Material

A 2D + 2D → 3D inclined polycatenated dynamic metal–organic framework of {[Cu(4-bpe)(2-ntp)(H 2 O) 2 ]·2H 2 O} n [ 1, where 2-ntp 2– = 2-nitroterephthalate and 4-bpe = 1,2-bis-(4-pyridyl)ethane] has been synthesized and characterized. The variable-temperature powder X-ray diffraction study indicates the dynamic nature of the inclined polycatenated framework, and the dehydrated framework with exposed metal centers exhibits excellent type I H 2 adsorption of 1.94 wt % at 77 K and 1 bar of pressure.
