Abstract
- Abstract: Two new cadmium coordination polymers namely [Cd(HAmTrz–COO)4(NH4 +)2] 1; and [Cd(HAmTrz)2I2]n 2; (HAmTrz–COOH=3-amino-1,2,4-triazole-5-carboxylic acid), have been prepared based on HAmTrz–COOH as ligand. The crystal structures of 1 and 2 have been determined by single-crystal X-ray diffraction technique. In coordination-complex 1 four triazole ligands coordinate via N1 nitrogen leading to a tetrahedral geometry around cadmium ion, while in 2 the ligand prefers to coordinate to the metal in a bidentate bridging mode. The structures of both the coordination polymers can be envisaged as 3D hydrogen bonded networks. Thermogravimetric analysis shows that 2 is more stable than 1 owing to different coordination numbers of cadmium atoms. Photoluminescence properties of both the compounds have been investigated in the solid state. [Copyright &y& Elsevier]
