چکیده
Redox active polyiron complexes with higher dimensional spacers, the tetrairon complex with the two-dimensional tetra(ethynylphenyl)ethene spacer, (C=C)[p-C(6)H(4)-C triple bond C-FeCp*(dppe)](4), and the diiron complex with the three-dimensional spacer (pseudo-m-[2,2]paracyclophane)[C triple bond C-FeCp*(dppe)](2), are prepared, and their performance as molecular wires is evaluated on the basis of their comproportionation constants for the mixed valence state.
