A pair of air-stable double-decker Dy(III) macrocyclic enantiomers featuring sole fluoride axial ligands were designed and structurally and magnetically characterized. They displayed strong intramolecular ferromagnetic coupling and two-step relaxation of magnetization supported by the collinear arrangement of the magnetic anisotropy axes and obviously different outer Dy-F distances for two Dy(III) ions, respectively.
