Incorporation of highly Lewis acidic redox‐inactive cations into multimetallic complexes is an emerging strategy for rational design of metal complexes. We present compounds in which a nickel salophen fragment was positioned in close proximity to Y 3+ , Nd 3+ , Ca 2+ , and Na + metal centers by employing a divergent synthetic strategy on a macrocyclic ligand platform. The reduction potential of the nickel salophen core is modulated by the Lewis acidity of the redox‐inactive ion (70 mV per p K a unit), suggesting these effects may be usefully exploited in tuning of redox catalysts.
