N3O3 Hexanuclear Complexes type are Synthesized and Characterised from the reaction of Diphenylmonoxime with (Mn(II),Co(II),Ni(II),Cu(II),Zn(II), and Hg(II)) ions.


The new Hexadentate complexes type [M(H3L3)]K were prepared from the condensation reaction of Diphenylmonoxime and KOH with (Mn(II), Co(II), Ni(II), Cu(II), Zn(II), and Hg(II)) in methanol with 3:1 ligand : metal ratio to give a series of new complexes of the general formula [M(H3L3)]K (where: M(II) = Mn ,Co ,N ,Cu ,Zn and Hg).All compounds have been Characterized by spectroscopic methods [I.R, U.V-Vis, atomic absorption and microanalysis (C.H.N) along with conductivity measurements. The stability constant K and Gibbs free energy ΔG were calculated for [Co (H3L3)] K, [Ni (H3L3)] K and [Cu (H3L3)] K and complexes using spectrophotometer method. The obtained values indicate that these complexes stable in their solution. From the above data the proposed molecular structure for complexes (Mn(II), Co(II), Ni(II), Cu(II), Zn(II), and Hg(II)) is octahedral structure about the metal ions. The biological activity for the ligand and some its complexes were studied.
