The electrochemical behaviour of the title complex shows two reversible le oxidations centred on the ferrocenyl moieties, indicating a moderate electronic communication between such redox units through the organic chain and the Pt binge. Moreover, two irreversible le reductions are detected, and assigned to the stepwise Pt-II-->Pt-0 process. The transient Pt-I intermediate is somewhat stabilized by the electronic delocalization over the external ferrocenyl units. The assignment of the redox processes is carried out by comparison of the electrochemical behaviour of several model complexes, which represent the building blocks of the overall molecule.

Abstract
The electrochemical behaviour of the title complex shows two reversible le oxidations centred on the ferrocenyl moieties, indicating a moderate electronic communication between such redox units through the organic chain and the Pt binge. Moreover, two irreversible le reductions are detected, and assigned to the stepwise Pt-II-->Pt-0 process. The transient Pt-I intermediate is somewhat stabilized by the electronic delocalization over the external ferrocenyl units. The assignment of the redox processes is carried out by comparison of the electrochemical behaviour of several model complexes, which represent the building blocks of the overall molecule.
