The structure of Cu (C4H8NO3) 2] .H2O, a supramolecular complex of copper (Ⅱ) L-threonine, was synthesized and its structure was confirmed by elemental analysis, IR, DTA-TG, UV spectra and single crystal structure. The compound consists of one Cu (II) ion, two L-threonine anions and one crystal water, wherein the carboxyl oxygen atom and the amino nitrogen atom of the amino acid are coordinated with the copper (II) ion to form a six-coordinate pull Long octahedral configuration, the unit cell by intermolecular hydrogen bond to form a three-dimensional network of super-molecular system. The UV absorption wavelength of the complex in aqueous solution is 233 nm. The solid-state fluorescence emission forms a three-dimensional network of supramolecular systems by intermolecular hydrogen bonds. The UV absorption wavelength of the complex in aqueous solution was 233 nm and the solid-state fluorescence emission was at 357 nm. Electrochemical behavior showed that the complex was irreversible redox process at the glassy carbon electrode and the reaction process was controlled by diffusion.
