Abstract: Under hydrothermal conditions, two novel polyoxometalate (POM)-based CuⅡ and CuⅠ hybrid materials, namely[Cu2(4-NH2-trz)4(Mo8O26)(H2O)4]·5H2O (1) and[Cu4(4-NH2-trz)4Mo8O26] (2) (4-NH2-trz=4-amino-1,2,4-triazole) have been designed and synthesized. Their crystal structures have been determined by single crystal X-ray diffraction, FT-IR infrared spectra and powder X-ray diffraction analysis. In 1, bi-dentate 4-NH2-trz ligands bridge two neighboring CuⅡ centers forming dinuclear structural units, which are further linked by Mo8O264- ions and arranged into a one-dimensional (1D) hybrid coordination framework. In 2, bidentate 4-NH2-trz ligands also link neighboring CuⅠ centers to generate unique 1D[Cu4(4-NH2-trz)4]n helical chains. Further these infinite right-hand and left-hand helical chains are linked by (β-Mo8O26)4- anions to form a 2D hybrid framework. Photocatalytic activities for decomposition of different organic dyes (methylene blue (MB), rhodamine B (RhB) and methyl orange (MO)) have been investigated for 1 and 2, indicating that 1 and 2 are good candidates for the photocatalytic degradation of these organic dyes. |
