Strong intramolecular Dy^III–Dy^III magnetic couplings up to 15.00 cm⁻¹ in phenoxyl-bridged dinuclear 4f complexes

Unexpectedly, intramoleular DyIII–DyIII magnetic couplings are up to 15.00 cm−1 in the phenolate-bridged Dy2 complexes. And single-molecule magnet behavior is exhibited with effective energy of 76.18 K under zero dc field.
