Two Cd(II) and Zn(II) coordination polymers based on 3,3′,5,5′- azobenzenetetracarboxylic acid (H4abtc): [Cd2(abtc)(H 2O)6]·DMF·0.5H2O (1) and [Zn 2(abtc)(bpy)(H2O)2]·DMF·H 2O (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.
