• Solvent facilitated structure reversibility

Two Cd(II) and Zn(II) coordination polymers based on 3,3',5,5'-azobenzenetetracarboxylic acid (H(4)abtc): [Cd-2(abtc)(H2O)(6)]center dot DMF center dot 0.5H(2)O (1) and [Zn-2(abtc)(bpy)(H2O)(2)]center dot DMF center dot H2O (2) are synthesized and structurally characterized. Both 1 and 2 are 2D polymers but interconnected by solvent molecules to generate 3D suprastructures. Solvent expulsion leads to rupture of both structures, but upon re-exposure to the solvent mixture they exhibit remarkable ability to regain the original structure reversibly from the almost amorphous solvent-expelled form. Compounds with such structural flexibility and reversibility are expected to have some useful functionality.
