  text: Ferrocenes are ubiquitous organometallic building blocks that comprise a Fe
    atom sandwiched between two cyclopentadienyl (Cp) rings that rotate freely at
    room temperature. Of widespread interest in fundamental studies and real-world
    applications, they have also attracted some interest as functional elements of
    molecular-scale devices. Here we investigate the impact of the configurational
    degrees of freedom of a ferrocene derivative on its single-molecule junction conductance.
    Measurements indicate that the conductance of the ferrocene derivative, which
    is suppressed by 2 orders of magnitude as compared to a fully conjugated analogue,
    can be modulated by altering the junction configuration. Ab initio transport calculations
    show that the low conductance is a consequence of destructive quantum interference
    effects of the Fano type that arise from the hybridization of localized metal-based
    d-orbitals and the delocalized ligand-based π-system. By rotation of the Cp rings,
    the hybridization, and thus the quantum interference, can be mechanically controlled,
    resulting in a conductance modulation that is seen experimentally.
