摘要

Schiff base derived from 2-aminophenol and 3-formyl-2-hydroxy-6-methoxyquinoline and its Mn(II) and Fe(II) complexes were synthesized and characterized by melting point and decomposition temperature, elemental analysis, molar conductivity, infrared (IR) spectral analysis, atomic absorption spectroscopy (AAS) analysis, solubility test, and magnetic susceptibility. The Fourier-transform infrared spectroscopy (FTIR) spectral data of the Schiff base determined showed <span><span style="font-family:Verdana;">a band at 1622 cm</span>^{<span style="font-family:Verdana;"><span style="white-space:nowrap;"><span style="white-space:nowrap;"><span style="white-space:nowrap;">&#8722;</span></span></span>1</span>}<span style="font-family:Verdana;"> and this was assigned to the </span><i><span style="font-family:Verdana;">v </span></i><span style="font-family:Verdana;">(C=N), which is a feature of azomethine group.
