Fulvalene-Bridged Binuclear Complexes: Strongly Antiferromagnetically Coupled Ru III Ru III and Class II–III Mixed-Valence Ru III Ru II

Key Points

• This research aims to investigate the antiferromagnetic coupling in fulvalene-bridged binuclear complexes of ruthenium.
• Theoretical calculations were performed to analyze magnetic interactions.
• EPR spectroscopic techniques were used to evaluate electronic properties.
• EPR signals were absent, confirming diamagnetic behavior.
• The theoretical calculations supported the presence of antiferromagnetic coupling.
