摘要: The new aluminium based metal–organic framework [Al(OH)(O2C–C4H8–CO2)]·H2O denoted as Al-MIL-53-ADP-lp (lp stands for large pore) was synthesised under solvothermal conditions. This solid is an analogue of the archetypical terephthalate Al-MIL-53 on aliphatic single-chain linker molecule adipic acid (H2ADP, hexanedioic acid). In contrast to its aromatic counterparts, Al-MIL-53-ADP exhibits a structural breathing behaviour solely upon dehydration/rehydration. crystal structure anhydrous compound Al-MIL-53-ADP-np (np narrow determined by combination forcefield-based computations and Rietveld refinement powder X-ray diffraction data while hydrated form derived computationally force field methods Density Functional Theory calculations.
