Complex 1 displays a 2D layer structure through the linkage of bridging carboxyl oxygen and pyridine nitrogen atoms of the pydc ligand. Each Cd(II) center exhibits a distorted octahedral coordination environment with four carboxylate oxygen atoms and two nitrogen atoms from the pydc and 2-meim ligands. In 1, the pydc ligand exhibits a new coordination mode. The distances of adjacent Cd(II) atoms are 3.679 and 7.742 angstrom. The 2D layers are further linked by C-H.. .pi and pi...pi stacking to construct a 3D supramolecular structure. In order to assess the potential of 1 in gas storage and gas separation applications, molecular simulations were performed. Furthermore, 1 exhibits blue photoluminescence in the solid state at room temperature.ChemistryInorganic and nuclear chemistryCrystallographyA two-dimensional photoluminescent cadmium(ii) coordination polymer containing a new coordination mode of pyridine-2,3-dicarboxylate: synthesis, structure and molecular simulations for gas storage and separation applicationsJournal Article1873-3719316033100040Q14603
