Synthesis, Spectroscopic and Biological Activity of New Mononuclear Transition Metal Complexes of Macrocyclic Schiff Bases Derived from 1,1'-Diacetylferrocin

摘要

Two series of mono-nuclear complexes with tetradentate macrocyclic Schiff base ligands,derived from the condensation of 1,1'-diacetylferrocene with 1,3-diaminopropanein in the molar ratio 1:1 and 1:2 have been prepared.The structures of these ligands were elucidated by different spectroscopic methods.The two Schiff base ligands react with copper(II),nickel(II),cobalt(II),and Zinc(II)metal ions in the molar ratio 1:1.The structures of complexes were identified by elemental analyses,infrared,electronic spectra,1H-NMR,13C-NMR,magnetic susceptibility,conductivity measurement and TGA analysis.The ligands and the complexes show growth inhibitory activity against pathogenic bacteria and plant pathogenic fungi.
