The new tetradentate Sciff base ligand H2L(C6H8N2O4) type (N2O4) as donor atoms, namely [2,2׳ -(ethane-1,2- diylbis (azan-1-yl-ylidene )diacetic acid)] waspreparedfrom condensation of glyoxylic and with ethylenediamine in ethanol as a solvent in presence of drops of 48% HBr.Thestructure of
ligand (H2L) was characterized by, IR,U.V-Vis.,1H-,13C-NMR , Mass spectrophotometer, melting pointand elemental microanalysis C.H.N.
Metal complexes of the ligand(H2L) in general formula [M(L)(H2O)2],where M=Mn(II), Co(II), Ni(II), Cu(II) and Hg(II); L=(C6H8N2O4)weresynthesized and characterized by, Atomic absorption,FT- IR , U.V-Vis. spectra, molar conductivityandmagnetic susceptibility, (Co+2,Ni+2, Cu+2, Mn+2, Hg+2)complexes, it found that all complexes showed octahedral geometries.And in vitro tests for antibacterial and antifungal activity showed that most of the prepared compounds display a good activity toStaphylococcus aureus), (Escherichia coli) and (Candida albicans).
