Solvent inclusion in MOFs is common as these materials are porous. The lateral facets defining the profile of the hexagon (Figure ) and the petals of several double-deckers flowers from different batches and at different reaction times were indexed by using the CrysAlisPro index module (Figure ). The profiles of the petals belonging to flowers of the same double-decker crystals after 6 h of solvothermal reactions were delineated by either 4 or 6 lateral facets (Figure , left and center). The rounded profile related to the larger, later-stage petals could be best approximated by 9 lateral facets (Figure , right). The inferred hkl planes of the facets are indicated on the crystal structure (Figure ). The molecular profile of the structure exposed by these planes and the visualization of the molecular surfaces at the solvent interface is shown in Figure .
