摘      要：A novel complex [Zn（Im）2（A-glu）]-0.5H2O（Im = imidazole, A-glu = N-acetyi- L-glutamic acid） has been synthesized from the reaction of A-glu with Zn（CH3COO）2·2H20 in the presence of Im at 65 ℃, and structurally characterized by single-crystal X-ray diffraction. The complex crystallizes in tetragonai, space group P43212 with a = b = 8.9078（6）, c = 43.458（6） A, C26H36N10O11Zn2, Mr = 795.39, V= 3448.3（6） A^3, De = 1.532 g/cm^3, Z = 4,μ（MoKα） = 1.461 mm^-1, F（000） = 1640, the final R = 0.0453 and wR = 0.0992. X-ray analysis reveals that the crystal structure is constructed by mixed iigands. A-glu adopts the bis-monodentate coordination mode linking two adjacent metal ions to form a one-dimensional chain. Zinc（Ⅱ） ions are four-coordinated with a distorted tetrahedral geometry. Luminescent properties of the complex have been inves- tigated.
