摘要: An unusual tetrazole-based Cd(II) coordination polymer, [Cd(4-tzba)(H2O)]n (tzba = 4-(tetrazolyl)benzenecarboxylic acid) (1), was synthesized by hydrothermal reaction and structurally characterized single-crystal X-ray diffraction. The structure of 1 contains distorted octahedral cadmium centers coordinated four different tzba2− ligands a water molecule. All the display type, μ4-κN1:κN3:κN4:κO1, O2, which connects atoms to form an intricate 3-D network. There are three kinds apertures in 1; two helical channels hexagonal aperture observed along axes. Polymer exhibits selective gas adsorption behavior for methanol, ethanol water. In addition, shows blue photoluminescence mainly arising from intraligand transitions aromatic rings tbza2− ligand.
