The redox chemistry of (p-butatriene)hexacarbonyldiiron compounds, Fe2(CO)6(RR’C=C=C=CRR’), has been investigated by electrochemical and spectroscopic methods and Fenske-Hall quantum-chemical calculations. The sequence of the electrode processes has been postulated on the basis of the response of different electrochemical techniques, electron spin resonance (ESR) spectroscopy, and chemical tests. The butatriene chain, interacting with the bimetallic Fe2(CO)6f ramework in a multicentered u / r fashion, is able to stabilize the electrogenerated anions.

Abstract
The redox chemistry of (p-butatriene)hexacarbonyldiiron compounds, Fe2(CO)6(RR’C=C=C=CRR’), has been investigated by electrochemical and spectroscopic methods and Fenske-Hall quantum-chemical calculations. The sequence of the electrode processes has been postulated on the basis of the response of different electrochemical techniques, electron spin resonance (ESR) spectroscopy, and chemical tests. The butatriene chain, interacting with the bimetallic Fe2(CO)6f ramework in a multicentered u / r fashion, is able to stabilize the electrogenerated anions.
