Abstract

Graphical abstract: In this study, 3D metal organic framework, namely [Zn2 (μ4 -o-pda)2 (μ-abpy)] n (1 ), has been synthesized under hydrothermal conditions with o-phenylenediacetic acid (o-H2 pda) and 4, 4′-azobis(pyridine) (abpy) ligands.1 has a binodal (3, 7)-connected 3D framework with the point symbol of (3.5 2 )(3 2 .4 4 .5 7 .6 7 .7).1 may be used as an effective adsorbent for H2 storage applications. Abstract: A new three-dimensional (3D) metal organic framework, [Zn2 (μ4 -o-pda)2 (μ-abpy)] n (1 ), has been synthesized by the hydrothermal reaction and characterized by FT-IR spectroscopy, elemental analysis, thermal analysis, X-ray powder diffraction, and single crystal X-ray diffraction techniques (o-H2 pda = o-phenylenediacetic acid and abpy = 4, 4′-azobis(pyridine)). Single crystal X-ray diffraction study reveals that complex1 exhibits a binodal (3, 7)-connected three-dimensional framework (3D) with the point symbol of (3.5 2 )(3 2 .4 4 .5 7 .6 7 .7). Thermal analysis reveal that complex1 is stable up to 300 °C. In order to investigate the potential of1 in gas storage applications, we performed experiments and atomically detailed simulations to obtain H2 adsorption isotherm at a pressure range of 0–1 atm at 77 K.
