Coordination polymers (CPs) are a kind of inorganic-organic hybrid materials that have received increasing attention recently due to their high porosity, stability, and modifiability. In this work, we have successfully synthesized a new CP based on a N-rich ligand (4,5-di(1H-tetrazol-5-yl)-2H-1,2,3-triazole) under hydrothermal condition. The crystal structure was determined by single-crystal X-ray diffraction. Compound 1 displays a three-dimensional supramolecular structure constructed from the two-dimensional layers, and has been further characterized by powder X-ray diffraction, elemental analysis, infrared spectrum, and thermogravimetric analysis. The electrochemical properties of compound 1 have been studied in detail. The detection performance of compound 1 modified electrodes was determined. The results reveal that compound 1 can be successfully applied as an electrode material to simultaneously detect two heavy-metal ions Cd2+ and Pb2+ with high sensitivity and selectivity. Moreover, compound 1 reveals excellent reversible capacity, cycle stability, and rate performance as an anode material for lithium-ion battery. In this work, a new CP [CuL(H2O)]·H2O (1) based on a N-rich ligand has been synthesized under hydrothermal condition. The structure and electrochemical properties of compound 1 have been studied in detail.
