An axial perturbation leading to enhanced magnetic and electronic properties of an acetate‐bridged, palladium–gadolinium complex ( 1 ) is reported. Pd 2+ donated electron density to Gd 3+ in an unusual fashion despite having an electron deficient d 8 structure. Consequently, 1 showed the highest pre‐exponential factor for spin relaxation reported so far for any Gd‐based molecular magnet exhibiting slow magnetic relaxation. A series of spectroscopic, theoretical, and magnetic studies showed that incorporating such metal–metal (TM‐Ln) interactions will be a powerful strategy in the design of smart magnetic and electronic materials.
