Structural, Characterization, Biological Activity And Thermal Study Of New Complexes [Ni Ii, Hg Ii And La Iii ] From Mixed Ligands (Curcumin And Azo Compounds) Type N3o2

Abstract

4-methoxyanilinereaction with 2-aminobenzothiazol in cold concentrated hydrochloric acid with 10%
NaNO2 to produce compound [L]. Compound [L] was reacted with curcumin and some transition metals
complexes [ Ni(II), Hg(II) and La(III)] in EtOH toyield new complexes. The structure of synthesized
complexes described via FTIR , UV-Visible Spectroscopy, TGA-DSC ,A.A., chloride content, conductivity and
the elemental analysis (CHNS).Complexes showed biological activity towards the E-coli (G-), Pseudomonas
(G-),S. aureus (G+), Proteus (G-) and fungi.Based on the results that have been obtained from the above
approaches, the proposed geometrical structures for every prepared complexhave been of the octahedral
formula.
