Fig. 1. (a) View of the coordination environment for ligand L– and the Al(iii) centre. (b) View of the corner-sharing octahedral chain of [AlO4(OH)2]···Cl. The μ2-(OH) groups form hydrogen bond to Cl–. Views of (c) MFM-305-CH3 and of (d) MFM-305. The pore size is ∼4.6 × 4.6 Å for MFM-305-CH3 and ∼5.6 × 5.6 Å for MFM-305 taking into consideration van der Waals radii. The methyl groups (olive) and chloride ions (green) in MFM-305-CH3; N atoms (blue) and hydroxyl group (olive) in MFM-305.
