| 摘 要： | A new nickel（Ⅱ） complex, C34H38N8NiO4, has been prepared and characterized by X-ray diffraction analysis. It crystallizes in the monoclinic system, space group P21/c with a = 11.715（5）, b = 12.328（5）, c =11.113（5）A, β= 92.589（5）°, Z = 2, Dc = 1.411 g/cm^3,μ = 0.658 mml, the final R = 0.0427 and wR = 0.1099 for 2229 observed reflections with I 〉 2σ（I）. The complex is a centrosymmetric plane in which nickel（Ⅱ） is coordinated in a regular octahedron to the ligand phenytoin through the nitrogen atoms of ethylenediamine, imine and amine. The complex was valued for its antimicrobial activity against bacterial strands using the agar diffusion method, and found to be active against the four test bacterial organisms. Preliminary screening for antimicrobial activities showed that the title complex is quite active against standard strains of Salmonella species, Staphylococcus aureus, Bacillus pumilus and Eschierichia coli.
