| Abstract | ||
| The compound (4-dimethyl amino benzadehyde) react with (1,2-diamino ethane) to form new Sciff base [N,N'-Bis(4-dimethyl amino benzaldene-1,2-diaminoethane)] (DABE) .The product was characterized by (FT-IR) and thermal analysis (TG-DTG) . (DABE) act as a ligand coordinating with the metal ions [Pd(II),Ru(III) and Pt(IV)] through nitrogen of the isomethene group .The stereochemistry around the metal ion has been suggested using flame atomic absorption technique , FT-IR and UV-Vis. Spectroscopy , in addition to magnetic susceptibility, conductivity measurement and thermal analysis (TG-DTG) . The study of the nature of the complexes formed in (ethanolic solution ) following the mole ratio method , gave results which were compared successfully with those obtained from solid state studies . The apparent stability constant of the complexes have been studied with the time and their color were stable for more than (6) hours, as well as the molar absorptivites have been calculated. The antibacterial activity for the ligand and their metal complexes were studied against two selected micro-organisms (E.coli) and (Bacillus). | ||
