A new fused ring compound, 2,6-dibutyl-4,8-dimethyl-1,5-dihydro-s-indacene (VII) (H2L), has been synthesized from 2,5-dimethyl-1,4-dibromomethylbenzene in almost quantitative yield. Two organomtallic binuclear complexes, [Cp*Fe-L-FeCp*] (1) and the mixed-valence compound [Cp*Fe-L-FeCp*]+ BF–4 (2), have been characterized by spectroscopic and electrochemical techniques. The cyclic voltammogram of 1 exhibits a potential difference of 668 mV between two redox peaks and the UV-vis-NIR spectra of compound 2 shows an intervalance charge transfer band at 1794 nm. The information gathered by these techniques indicates that the studied binuclear complex has strong interaction between the two metal centres.
