Six new ferrocene based donor acceptor complexes containing thiophene and furan in the conjugation chain have been synthesized by conventional methods and characterized by NMR, electronic absorption spectral and electrochemical methods. X-ray single crystal structures of three thiophene derivatives, [(C 5 H 5 )-Fe-(C 5 H 4 CH CH-C 4 H 3 S)] (la), [(C 5 H 5 )-Fe-(C 5 H 4 -CH CH-C 4 H 2 S-CHO)] (2a) and [(C 5 H 5 )-Fe(C 5 H 4 -CH CH-C 4 H 2 S-CH C(CN) 2 )] (3a) have also been determined. Electronic absorption spectral and electrochemical studies suggest that π-donor acceptor interactions are facile in thiophene derivatives when compared to their benzene analogues.
