Abstract: Using the 3-(1H-tetrazole-1-acetic acid amido) pyridine (TAAP）, Andersontype polyoxoanions and copper chloride as raw materials, we synthesized a new Anderson-type polyoxometalate-based copper complex {H₂Cu₁₂(Trz)₁₂［CrMo₆(OH)₆O₁₈］₂(OH)₈(H₂O)₄}·12H₂O. (HTrz=1Htetrazole). The crystal structure analysis shows that the complex is a twodimensional metalorganic layer formed by Trz ligand and Cu²⁺ ions. The terminal oxygen atoms of the［CrMo₆(OH)₆O₁₈］-3- polyoxoanions is connected to the Cu²⁺ ions to further form a threedimensional coordination framework. In situ conversion of TAAP ligand to Trz during the hydrothermal synthesis. The synthesized complex has good electrocatalytic reduction effect on H2O2, and good catalytic degradation effect on methylene blue and crystal violet under ultraviolet light.

Key words: Anderson-type polyoxometalate, copper complex, hydrothermal synthesis, electrocatalytic property, photocatalytic performance
