A zinc(II) metal−organic framework with high affinity for CO2 based on triazole and tetrazolyl benzene carboxylic acid

A new metal-organic framework {[Zn-2(Htzba)(2)(dmtrz)]center dot(CH3)(2)NH}(n) (1) that has already been solvothermally synthesized exhibits a high CO2 uptake capacity based on experimental and simulation calculation results. Furthermore, the selectivities to CO2/CH4 and CO2/N-2 are predicted by IAST to be 41.19 and 46.21 at 298 K and 100 kPa, respectively. The superior performance suggests that 1 is a promising candidate for CO2 separation.
