A novel zinc(II) metal–organic framework with a diamond-like structure: synthesis, study of thermal robustness and gas adsorption properties
Original language description
A solvothermal reaction of Zn(II) salt with methanetetrabenzoic acid (H4MTB) and 1,4,8,11-tetraazacyclotetradecane (cyclam, CYC) created a new microporous metal–organic framework {[Zn2(μ4-MTB)(κ4-CYC)2]2DMF7H2O}n (DMF = N,N-dimethylformamide). Single crystal X-ray diffraction showed that the complex exhibits a four-fold interpenetrated diamond-like structure topology with 1D jar-like channels with sizes about 14.1 14.1 and 2.4 2.4 Å2. The stability of the framework and activation conditions of the compound have been studied by high-energy powder X-ray diffraction during in situ heating, thermogravimetric analysis coupled with mass spectrometry and infrared spectroscopy performed at different temperatures. The gas adsorption behaviour of {[Zn2(μ4-MTB)(κ4-CYC)2]2DMF7H2O}n was studied by adsorption of Ar, N2, CO2 and H2. Nitrogen and argon adsorption showed that the activated sample exhibits Brunauer–Emmet–Teller (BET) specific surface areas of 644 m2 g1 (N2) and 562 m2 g1 (Ar). The complex adsorbs carbon dioxide with a maximum storage capacity of 10.5 wt% at 273 K and 101 kPa. The observed hydrogen uptake was 1.27 wt% at 77 K and 800 Torr, which is the highest value reported for the compounds containing a MTB4 linker. The adsorption heats of carbon dioxide and hydrogen, calculated according to the Clausius–Clapeyron equation, were in the range 22.8–22.4 kJ mol1 for CO2 and 8.9–3.2 kJ mol1 for H2, indicating weak interactions of the gases with the framework.n
