Abstract

Field induced single-molecule-magnet behaviour is observed for both a heterodinuclear [ZnDy(L^-)₂]³⁺ complex (1) and a mononuclear [Dy(HL)₂]³⁺ complex (2), with effective energy barriers of 83 cm^-1 and 16 cm^-1, respectively. Insights into the relaxation mechanism(s) and barrier heights are provided via ab initio and DFT calculations. Our findings reveal an interesting observation that the U_eff of SMMs can be enhanced by incorporating diamagnetic metal ions. This journal is
