Graphical Abstract

An axial perturbation leading to enhanced magnetic and electronic properties of an acetate-bridged, palladium–gadolinium complex (1) is reported. Pd2+ donated electron density to Gd3+ in an unusual fashion despite having an electron deficient d8 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. More information can be found in the Full Paper by D. C. Izuogu, T. Yoshida, M. Yamashita, et al. on page 9285.
