Syntheses of four porous 3-D Cd(ii) metal–organic frameworks from a new multidentate ligand 5-(imidazol-1-yl)-N′-(pyridin-4-ylmethylene) nicotinohydrazide and their characterization and adsorption properties

Herein, four stable 3D porous Cd(ii)-MOFs were constructed from the multidentate acylhydrazone ligand, and their CO₂ adsorption properties revealed that the anions have an obvious effect on the adsorption capacities of these MOFs.
