Synthesis and Study of Spectral Characterization of N2O2 Type Schiff Base Metal Complexes


Novel N2O2 type Schiff base and its metal complexes of Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) have been synthesized from the Schiff base (H2L) 4[N-(2-hydroxyacetophenone)imino]antipyrinyl-2-amino-2methyle-1-propanol derived from 4-aminoantipyrine, o-hydroxyacetophenone and 2 – amino – 2 – methyl – 1 - propanol. Structural features of the complexes have been deduced from metal analyses, infrared, electronic spectra, magnetic susceptibility and conductivity measurements. All complexes were found to have the composition of [ML] type. IR spectra show that the ligand is coordinated to the metal ions in a tetradentate manner. The electronic and magnetic susceptibility data of the complexes suggest a square planar geometry around the central metal ion. The molar conductance data reveal that the complexes are non-electrolytes
