A tuneable hierarchical self-assembly of a C3-symmetric triaminoguanidinium-derivative into a rhombic dodecahedral morphology

A crystalline rhombic dodecahedral shape with a size up to 23.7 mu m via the self-assembly of a C-3-symmetric triaminoguanidinium derivative has been reported. Structural evidence confirms the preferential occupancy of the solvent molecules in the (110) crystal facet over (100), favouring the growth direction for realizing such morphology.
