N-R-1-N-R-2-4,4-Bipyridinium and N-R-1-4,4-bipyridinium salts containing ferrocenyl substituents were prepared as donor-acceptor compounds (R-1 = ferrocenyl, ferrocenylphenyl; R-2 = ferrocenyl, ferrocenylphenyl, phenyl, methyl). Platinum(II)-bridged diferrocene compounds were prepared by using the N-R-1-4,4-bipyridinium ligands. These compounds display multistage redox properties. The redox potentials of the ferrocenyl and bipyridinium moieties in these compounds are independently affected by molecular modifications, which indicates that conjugation between the donor and acceptor moieties is less effective. Single-crystal X-ray diffraction analyses revealed large twist angles between the two moieties in the solid state. The compounds exhibit broad charge-transfer absorption bands in the range 450-800 nm. No electronic communication was observed between the terminal ferrocenes in the diferrocene complexes.
