Two New Cd(II) Coordination Polymers Based on Triazolyl Derivative and Different Carboxylate Ligands, Their Crystal Structures and Properties

Two new mixed-ligand coordination polymers of Cd(II), namely, [Cd(H 2 L)(ip)H 2 O] n ( 1 ) and [Cd(H 2 L)(Hbtc)] n ( 2 ) [H 2 L = 3-(1H-pyrazol-4-yl)-5-(pyridin-2-yl)-1,2,4-triazole, H 2 ip = isophthalic acid, H 3 btc = 1,3,5-benzenetricarboxylic acid], have been hydrothermally synthesized and characterized by elemental analysis, IR spectra, powder X-ray diffraction, and single-crystal X-ray diffraction. Compound 1 displays a one-dimensional chain structure, which upon hydrogen bonding generates 3D supramolecular framework. Compound 2 exhibits a one-dimensional double-chain structure connected by hydrogen bonds with formation of 2D supramolecular framework. Fluorescent properties of two compounds have been studied in the solid state at room temperature.
