Addition of excess praseodymium(III) nitrate or Perchlorate to aqueous solutions of sodium p-sulfonatocalix[4]arene (Na5SO3[4]) results in the formation of a 3-D coordination polymer and a 4:3 Pr/SO 3[4] complex, respectively. Concentration of the solution containing crystals of the latter resulted in the dissolution and regrowth of crystals that were subsequently found to be a bilayer arrangement of SO3[4] containing Perchlorate anions, therefore suggesting that concentration effects may be an important route to new supramolecular architectures based on the versatile host.
