Abstract:

We report on the synthesis and properties of a family of linear cyanide bridged mixed-valence heptanuclear complexes with the formula: trans-[L 4RuII{(μ-NC)FeIII(NC)4(μ-CN) RuIIL′4(μ-NC)FeIII(CN) 5}2]6- (with L and L′ a para substituted pyridine). We also report on the properties of a related pentanuclear complex. These oligomers were purified by size exclusion chromatography, characterized by electrospray ionization (ESI) mass spectrometry and elemental analysis, and their linear shape was confirmed by scanning tunneling microscopy (STM). These complexes present a rich electrochemistry associated with the seven redox active centers. The redox potential split of identical fragments indicates that there is considerable communication along the cyanide bridged backbone of the compounds, even for centers more than 3 nm apart. This small attenuation of the interaction at long distances make these cyanide bridged compounds good candidates for molecular wires. Interestingly, the extent of the communication depends on the relative energy of the fragments, as evaluated by their redox potentials, providing a guide for improvement of this interesting property. © 2009 American Chemical Society.

  • The orientation of the cyanide bridge is expected from the connectivity in the precursors. In previous work we did not find isomerization of the cyanide bridge and in one case we have prepared the two possible isomers (see ref 5, The properties of the two isomers are quite distinctive, especially their redox behavior. Isomerization of the bridge results in an increase in the redox potential of the RuII/III couple, while the FeIII/II couples become more irreversible because of the lability of the Fe-N(nitrile) bond. Our exploration of the redox properties of the complexes reported here show no evidence of bridge isomerization; Flanagan, J.B., Margel, S., Bard, A.J., Anson, F.C., (1978) J. Am. Chem.
