A new microporous metal-organic framework Cu2(PDDI) (ZJU-5; H4PDDI = 5,5'-(pyridine-2,5-diyl)diisophthalic acid) was solvothermally synthesized and structurally characterized. With open metal sites, Lewis basic pyridyl sites and suitable pore space, the acetylene uptake in ZJU-5a reaches the highest one of 290 cm3/g at 273 K and 1 bar. Furthermore, ZJU-5a exhibits high absolute methane storage of 190 cm3(STP)/cm3 at 35 bar and 224 cm3(STP)/cm3 at 60 bar at room temperature.
