Strung out : Fe II complexes containing pairs of planar terdentate N ligands form regular one‐dimensional aggregates on highly oriented pyrolytic graphite, on a length scale of hundreds of nanometers. STM spectroscopy was used to probe the molecular conductance and thus the spin state. The distribution of spin states is random in the single‐molecule chain, but local cooperativity sets in when the chain is made up of oligonuclear “beads” (see picture).
