【Abstract】 A supermolecular complex [Cu（C₄H₈NO₃）₂]·H₂O 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 with two oxygen atoms from neighboring L-threonines.Various hydrogen bonds,such as O-H…O,N-H…O,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.更多还原
