A supermolecular complex [Cn (C_4H_8NO_3)2] ·H_2O was synthesized and characterized by elementary analysis, IR, UV, TG and DTA and crystal X-ray diffraction analysis. TG and DTA revealed that the complex contains one molecule of crystal water. The analysis of crystal structure indicates that it consists of a Cu(Ⅱ) ion, two L-threonine and a crystal water molecules. The coordinate geometry of the Cu atom was a distorted square planar configuration. The 1-D elongated octahedral chain structure was formed by the four-coordinated Cu (Ⅱ) ion presented in the 2-D chain structure and 3-D supermolecular system. The complex displayed a distinct absorption band at 233nm in aqueous solution and a photoluminescent band at 357 nm in solid state. The electrochemical behavior of the complex showed an irreversible wave which controlled by the diffusion process.
