A further interesting point concerns the direction of the petal growth. The complex morphology comprises 12 petal subunits having a radial disposition. The petal subunits express their growth direction at all the evolution stages, even when strong size inhomogeneity is present within the subunits belonging to the same structure. This fact suggests, once more, the guiding role of the underlying crystal structure. Modern computational tools are being applied nowadays to predict and aid in the design of the molecular packing of crystals, theoretical methods are also much needed for the understanding of complex morphologies of MOFs. We envisage that for this class of material, and other low-density structures, intriguing shaping capability may become increasingly more prominent as additional examples are discovered. The XRD patterns were analyzed and fitted using Jade Pro 2010 software (Materials Data, Inc.).
