An exceedingly rare porous metal–organic framework that is based on cadmium ions and multi carboxylate ligands, namely, Na 0.25 [(CH 3 ) 2 NH 2 ] 1.75 [Cd(L) 2 ] ⋅ x solvent ( 1 , H 2 L=2‐hydroxymethyl‐4,6‐bi(2′‐methoxyl‐4′‐(2′′‐1′′‐carboxyl)‐ethlene)‐1,3,5‐mesitylene), has been successfully synthesized under solvothermal conditions. Compound 1 exhibits a 2D network that is constructed from left‐ and right‐handed helical chains. Furthermore, neighboring 2D layers are stacked to give a porous motif. Strikingly, compound 1 exhibits the highly efficient exchange of metal ions from the main framework components whilst maintaining the structural integrity and the crystallinity of the network. In addition, Compound 1 also shows outstanding performance in the reversible adsorption of iodine.
