While chiral crystal structures are numerous, the dissymmetry in structure is not always manifested in the morphology. Here, we analyzed a MOF whose dissymmetric crystal form can be tailored by the solvent composition. Pasteur famously had established a correlation between the macroscopic for 24 h resulting in the formation of crystals on the surface of the vial which were collected by using filtration under reduced pressure. A white powder was obtained after drying under vacuum (~10 -2 mbar, 82% yield based on AdDB). Larger crystals can be obtained by decreasing the concentration of the starting materials by adding 0.5 mL of DMF (Fig. ).
