Hierarchically nano/microstructured coordination polymer Pr(1,3,5-BTC)(H2O)6 architectures with different crystal splitting forms have been successfully prepared on a large scale via direct precipitation in the solution phase. The as-obtained samples present highly crystallinity in spite of the moderate reaction conditions. The morphology and size of the products strongly depend on the concentration, molar ratio of reactants, reaction temperature, solvent, surfactant, and static reaction; thus, 3D flower, straw-sheaf, chrysanthemum-sheaf, dendrite-sheaf, fan, bundle without fantails, broccoli, embryo superstructures, and 1D nanorod of the coordination polymer can be perfectly manipulated by controlling the above reactions parameters rationally.
