Abstract:
The present communication deals with the result of the Schiff base ligand 3-amino 2 ethyl quinazoline 4(3H) Semicarbazone (AEQS) with bivalent transition metal ions, Cu(II), Co(II) and Ni(II). The ligand and its metal complexes are characterized on the basis of molar mass, elemental analyses, IR, electronic spectra, molar conductivity, magnetic moment measurement. The reaction of the ligand with Cu(II), Co(II) and Ni(II) resulted in the formation of the complexes have the general composition [M(AEQS)2]X2 where M= Cu(II), Co(II) and Ni(II). AEQS=3-amino 2 ethyl quinazoline 4(3H) semicarbazone and X = Cl-, Br- or I-. The studies proposes a distorted octahedral geometry for Cu(II) complexes where as octahedral geometry is assigned for Cu(II), Co(II) and Ni(II) complexes.
