Redox-active polyiron complexes with tetra(ethynylphenyl) ethene and [2,2]paracyclophane spacers containing ethynylphenyl units: extension to higher dimensional molecular wire

摘要

Redox active polyiron complexes with higher dimensional spacers, the tetrairon complex with the two-dimensional tetra( ethynylphenyl) ethene spacer, (C=C)[p-C6H4-C = C-FeCp*(dppe)]4, and the diiron complex with the three-dimensional spacer (pseudo-m-[2,2] paracyclophane)[C equivalent to 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.
