Insight into ferromagnetic interactions in Cu^II-Ln^III dimers with a compartmental ligand.

ABSTRACT: In the last two decades, efforts have been devoted to obtaining insight into the magnetic interactions between Cu^II and Ln^III utilizing experimental and theoretical means. Experimentally, it has been observed that the exchange coupling (J) in Cu^II-Ln^III systems is often found to be ferromagnetic for ≥4f⁷ metal ions. However, exchange interactions at sub-Kelvin temperatures between Cu^II and the anisotropic/isotropic Ln^III ions are not often explored. In this report, we have synthesized a series of heterobimetallic [CuLn(HL)(μ-piv)(piv)₂] complexes (Ln^III = Gd (1), Tb (2), Dy (3) and Er (4)) from a new compartmental Schiff base ligand, N,N'-bis(3-methoxy-5-methylsalicyliden
