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(H2L)(ip)H2O]n (1) and [Cd(H2L)(Hbtc)]n (2) [H2L = 3-(1H-pyrazol-4-yl)-5-(pyridin-2-yl)-1,2,4-triazole, H2ip = isophthalic acid, H3btc = 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. [ABSTRACT FROM AUTHOR]
