Structural building units (a) of the target MIL-53(Al) metal-organic framework (MOF): the benzenedicarboxylate (BDC) linker and the octahedral aluminium-oxo metal node (inset). Coordination geometry (b) where the ligand carboxylate group (COO) bridges adjacent metal centers. Crystal structures (c) of the narrow-pore, np, and the large-pore, lp, forms of a MIL-53 MOF. |
