An unusual tetrazole-based Cd(II) coordination polymer, [Cd(4-tzba)(H 2 O)] n (tzba = 4-(tetrazolyl)benzenecarboxylic acid) ( 1 ), was synthesized by hydrothermal reaction and structurally characterized by single-crystal X-ray diffraction. The structure of 1 contains distorted octahedral cadmium centers coordinated by four different tzba 2− ligands and a water molecule. All the tzba 2− ligands display coordination of type, μ4-κN1:κN3:κN4:κO1, O2, which connects four Cd(II) atoms to form an intricate 3-D network. There are three kinds of apertures in the structure of 1 ; two helical channels and a hexagonal aperture are observed along different axes. Polymer 1 exhibits selective gas adsorption behavior for methanol, ethanol and water. In addition, 1 shows blue photoluminescence mainly arising from intraligand transitions of the aromatic rings in the tbza 2− ligand.
