  Synthesis, characterization and computational studies of zinc(II)-halide complexes with a bidentate schiff base ligand (2,5-MeO-ba)2En: The crystal structure of (2,5-MeO-ba)2En

  摘要：

  In this study four coordinated complexes of zinc(II) halides with a new symmetrical bidentate Schiff base ligand (2,5-MeO-ba)(2)En are synthesized and characterized. The metal to ligand ratio of the complexes is found to be 1:1 with the formula of Zn((2,5-MeO-ba)(2)En)X-2 (X = Cl (1), Br (2), I (3)). The crystal structure of the Schiff base ligand (2,5-MeO-ba)(2)En is determined by X-ray crystallography from single crystal data. Also, the optimized geometries of the Schiff base ligand (2,5-MeO-ba)(2)En and its zinc(II) complexes are calculated using the density functional theory method (B3LYP/6-31G). The obtained structural parameters of (2,5-MeO-ba)(2)En are in agreement with the experimental data.

  ethylenediamine were structurally and spectroscopically characterized. Thin layers of Cu(II) complexes were deposited on Si(111) or ZnO/Si(111) by a spin coating method. The Cu(II) layers exhibited fluorescence bands between 462 and 503 nm. In the Cu(II)complex/ZnO/Si layers, quenching of the emission band from ZnO at 440 nm (λex=330 nm) was noted.

  In this note, the synthesis and structure-activity relationships of a new series of 2R,2'R/2S,2'S and 2R,2'S-meso 3,3'-(1,2-ethanediyl)-bis[2-aryl-4-thiazolidinones] are described. Antiinflammatory activity was investigated by the carrageenin-induced paw edema test and analgesic activity by acetic acid writhing and hot plate tests in rats. All compounds displayed ulcerogenic effects and acute toxicity
