Abstract
Kinetics and Mechanism of Electron Transfer Reaction of an Adipato Bridged Iron(III)-Salen Complex with Dithionite Ion in Perchloric Acid Medium

T HE vital importance of iron and its compounds in the functioning of living organisms and metallurgical industries explains the vast interest of researchers in investigating its chemistry
In this report we investigate the reduction of bridged dinuclear Fe(III)-salen complex by dithionite ion, which hitherto
Spectrophotometric titration showed that one mole of S2O42– was consumed per mole of [(Fe(salen))2adi] reduced in accordance with Equation (2)
Summary
T HE vital importance of iron and its compounds in the functioning of living organisms and metallurgical industries explains the vast interest of researchers in investigating its chemistry. The rate data for reduction of the Fe(III) dimer, [(Fe(salen))2adi] and consequent oxidation of the dithionite ion were obtained as the decrease in the absorbance of the reacting mixture at 455 nm. Pseudo-first order decays were linear and fit equation (1) to above 88 % extent of the reaction, indicating first order dependence of rate on concentration of [(Fe(salen))2adi] (the oxidant).
