ABSTRACT:
A new quinoxaline derivative (L)8-methyl-11-oxo-Indeno (1, 2-b) quinoxaline was synthesized by a one step reaction between ninhydrin and 4-methyl-phenylenediamine . It formed metal complex when reacted with hydrated chlorides of Cr(III), Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) in ethanol–chloroform medium. The quinoxaline derivative (L) has, characterized on the basis of IR, NMR and UV-VIS spectral data. The metal complexes were characterized by analytical, conductivities, spectral (F.A.A.S, IR, UV-VIS) and magnetic data. Involvement of exocyclic carbonyl oxygen and one of the quinoxaline nitrogen in coordination was concluded, such that the ligand behaves as a neutral bi dentate. Conductance measurements indicate the electrolytic behavior of the complexes in 1:2 ratio except 1:1 ratio for chromium(III) complex .Electronic spectral and magnetic susceptibility data suggest square planar geometry for [NiL2 ]Cl2complex,tetrahedral symmetry for [ZnLCl2].H2O while the complexes of Cr(III), Mn(II),Co(II), and Cu(II) of general formul were octahedral with molecular formula [CrL2Cl2]Cl. H2O and [ML2(H2O)2]Cl2,M=Mn,Co and Cu(II) ions respectively.
