The binuclear [
5-(1-ferrocenyl)indenyl]Rh(NBD) (1), [5-(1-ferrocenyl)indenyl]Rh(COD)(1a), and [5-(1-ferrocenyl)indenyl]Rh(CO)2 (2) complexes have been synthesized (NBD =norbornadiene; COD = cycloocta-1,5-diene). The crystal structure determination showed thatthe iron and rhodium nuclei are disposed in a transoid configuration in 1 probably to avoidsteric repulsions. On the contrary, in 2 the metals are in a cisoid configuration due to thepresence of stabilizing 
-hydrogen bonds between the CO's and the hydrogens of theunsubstituted cyclopentadienyl ring. The results of the chemical and electrochemicaloxidation of 2 are in favor of the existence of an effective interaction between the two metals.
