摘要：

The spins of unpaired electrons in binuclear CrIII complexes containing the structural element A are coupled antiferromagnetically. Measurement of the temperature‐dependent susceptibilities showed that the contribution of this coupling is inversely proportional to the twelfth power of the intramolecular distance between the Cr ions (|J| ∼ r−12).
