A novel (3,4)-connected Cd(II)-coordination polymer with 3-fold interpenetration assembled from 5-Nitrobenzene-1,2,3-tricarboxylate and flexible 1,6-bis(imidazol-1-yl)-hexane ligands

Syntheses, structures and luminescence of two cadmium entangled coordination polymers based on bis(imidazole) and biscarboxylate ligands

“…1). The Cd1⋯Cd1C and Cd1⋯Cd1E, and Cd1B⋯Cd1C and Cd1B⋯Cd1E distances separated by bdc ligands are 6.5217 (14), 10.3581(22), 7.2685(21) and 10.9400(29) Å, respectively.…”

“…The metal ions and organic ligands are the key factors for assembling the coordination polymers with structural diversity. Flexible bidentate N-donor ligands such as bis(imidazole) ligands [9][10][11][12] are widely used to construct coordination polymers because flexible ligands can adopt different conformations according to the geometric needs of the different metal ions. In order to achieve flexibility, the ligands built from multiple functional groups linked by aliphatic chains have been widely investigated.…”
