Experimentally, it has been observed that the exchange coupling (<i>J</i>) 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, <i>N</i>,<i>N'</i>-bis(3-methoxy-5-methylsalicylidenDalton transactions (Cambridge, England : 2003)Insight into ferromagnetic interactions in Cu^II-Ln^III dimers with a compartmental ligand.PMC10845014UIDP/50011/202001/3118/23/EMR-IIDFG-CRC-1573LA/P/0006/2020ERC grant MoQuOS 741276ERC grant MoQuOS 741276.UIDB/50011/2020DFG-CRC 1573Novitchi GMoreno-Pineda EHerchel RJana NCPaul SWernsdorfer WPanja ABrandao PfalseInsight into ferromagnetic interactions in Cu^II-Ln^III dimers with a compartmental ligand.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.
