A new three-dimensional metal–organic framework 1 was solvothermally synthesized by 1,2,4-triazole and 2-aminoterephthalic acid, and structurally characterized. 1 features a three-dimensional structure with one-dimensional pores along the c axis of 6 × 6 Å2. Activated 1 exhibits an H2 uptake capacity at 77 K. Importantly, it shows excellent enthalpy of CO2 (35 kJ mol−1) and methane (24 kJ mol−1), compared to previous porous materials.
