Zeitschrift für anorganische und allgemeine Chemie, EarlyView.Remote symmetry breaking in Jäger‐type iron(II) complexes shifts stepwise spin crossover (SCO) profiles to continuous profiles with transition temperatures around room temperature. In a bottom‐up approach, we studied the feedback of slight molecular modifications on the spin crossover (SCO) properties of otherwise structurally conserved iron(II ...
