Synthesis , Characterization , and Study of Electrical Properties of Fe(III) and Al(III) Complexes of a Schiff base

A Schiff-base ligand derived from o-aminophenol and salicylaldehyde and its transition metal complexes with the metals Fe(III) and Al(III) have been synthesized. The prepared Schiff-bases and their complexes were identified by IR, UV-Visible and elemental analysis (CHN).These used techniques facilitated to elucidate the chemical structures of the chelates.These techniques show that both transition metals form complexes with Schiff base in the ratio 1:2[M:L]and in Octahedral structures. The electrical properties of Schiff-base and their complexes were studied over temperature range (0 -110 0C ) before and after dopping with iodine. the maximum value of conductivity was 1.81× 10-4 ohm-1 .cm-1 . for dopped aluminum complex.
