Abstract

We report the synthesis, structure and magnetic investigations of two new Dy³⁺ homoleptic ate-complexes based on different ene-diamido ligands [K(THF)₂][Dy(DAD^2R)₂] (R = H (1), Me (2) DAD^2R = [2,6-iPr₂C₆H₃N–CR [double bond, length as m-dash] CR–NC₆H₃iPr₂-2,6] showing K⁺/arene interactions. Magnetic investigations reval that both compounds exhibit a zero-field single-molecule magnetic relaxation mainly governed by a Raman process.
