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><sup><span style=\"font-family:Verdana;\"><span style=\"white-space:nowrap;\"><span style=\"white-space:nowrap;\"><span style=\"white-space:nowrap;\">&amp;#8722;</span></span></span>1</span></sup><span style=\"font-family:Verdana;\"> and this was
