A Ru carbon-​rich-​based ligand that brings redox reversibility to a dinuclear Dy-​based single-​mol. magnet, trans-​[PhC≡C(dppe)​2RuC≡C-​bipy-​κ2-​N,​N-​Dy(tta)​3] (tta = 2-​thenoyltrifluoroacetonate)​, is reported. Long-​distance perturbation of the 4f ion is achieved upon oxidn., resulting in an overall enhancement of the magnetic slow relaxation.
