Ferrotoroidic ground state in a heterometallic {CrIIIDyIII 6} complex displaying slow magnetic relaxation

Abstract

Coupling molecular toroids via ferrotoroidic interactions represents an important opportunity to enhance ground state toroidicity, but is challenging to achieve. Here the authors isolate a {CrIIIDyIII 6} complex with a ferrotoroidic ground state and an enhanced toroidal moment, arising solely from intramolecular dipolar interactions.
