| Abstract: In the recent years, there are many studies on the synthesis and activity of functional complexes. On the basis of preceding work, we have synthesized eight mixed ligand complexes of Cu(Ⅱ) with Schiff base derived from β diketone, salicylaldehyde and some aminoacid. Lignads of N,N′-(benzoyl acetonyl) phenylene diamine, N,N′-(diacetonyl) phenylene diamine, salicylaldehyde semicarbazone, benzoyl acetone semicarbazone, sodium salicylaldehyde histidine, potassium salicylaldehyde tyrosine, potassium benzoyl acetonyl histidine and potassium diacetonyl tyrosine are used respectively. Those have been characterized by elemental analyses, molar conductances, infrared spectra, UV spectra and TG-DTA analysis. Astudy preliminarily on the structures and characters for these compounds have been carried out in this article, and their bioactivity of restraining function to escherichia coli has also been discussed. According to all the data, the formulas of [Cu(C16H14N2)Cl2],[Cu(C11H12N2)Cl2],[Cu(C8H9O2N3)Cl2],[Cu(C12H16O2N6)]Cl2,[Cu(C13H11O3N3)(H2O)]· 3H2O,[Cu(C16H13O4N)(H2O)]· 2H2O,[Cu(C20H23O7N3)], [Cu(C15H21O7N3)] are estimated. |
