The here observed crystal growth might be general for the formation of analogous systems. The 1.5 h prisms obtained resemble the recently reported "stellate" crystals with re-entrant angles and multidomain morphologies ; however, there are differences in the lateral sides. The reported stellate crystals did not consistently show a medial seam or separation of layers. The current crystals have distinct lateral facets and a gap between the upper and lower layers. With more time (>1.5 h), they develop into a well-defined, doubledecker flower-like, two-layer morphology. Interestingly, the fully-developed doubledecker flowers obtained here also resemble the reported chiral yo-yo-like MOF crystals grown from a related ligand system. Those chiral crystals were grown from solution at room temperature but had an intermediate phase of hexagonal prisms with lateral facets, similar to the ones observed here. The reactivity of these facets apparently plays a key role in the formation of such morphologies.
