Abstract

Fe(III) complex of the hydrazone  from (E)-N'-(thiophen-2-ylmethylene)isonicotinohydrazide (HL) has been synthesized and characterized by elemental analysis, electrical conductance in non-aqueous solvents, FT-IR and electronic spectroscopies, room temperature magnetic measurement, electrochemistry study as well as by X-ray diffraction structure determination. In the complex, the ligand acts in its neutral bidentate form, coordinating through the carbonyl oxygen and azomethine nitrogen. A high spin octahedral geometry assigned to the Fe(III) complex were further confirmed by room temperature magnetic moment data. Elemental analysis showed that Fe(III) complex is composed of metal and ligands in a molar ratio of 1:1. This complex of Fe(III) is a neutral electrolyte in DMF solution. The electrochemistry study shows that a one electron process determined the electrochemical reaction is governed by an electron transfer with an irreversible process.  The structure of the complex has also been determined by X-ray diffraction revealing an octahedral environment around the Fe(III) ion.
