Robust metal-organic framework enforced by triple-framework interpenetration exhibiting high H2 storage density.
A microporous metal-organic framework 1 Zn 2(CNC) 2(DPT).G [CNC = 4-Carboxycinnamic; DPT = 3,6-Di-4-pyridyl-1,2,4,5-tetrazine; G = guest molecules] was synthesized and structurally characterized by a triply interpenetrated primitive cubic net with 1D pores of about 3.7 A. 1 is highly robust enforced by triple framework interpenetration through weak van der Waals interactions, thus the activated 1b takes up 1.28 wt % hydrogen gas and exhibits high hydrogen storage density of 95.2% at 1 atm and 77 K.
