Description
Summary:[Display omitted] •A brief introduction to single-molecule magnets is provided.•A description of the nature of superexchange interaction between Cu(II) and Ln(III) is provided.•Cu(II)-Ln(III) complexes of various nuclearities, that are single-molecule magnets, are described.•Examples of Cu(II)-Ln(III) complexes, that are single-chain magnets, are discussed.•Magneto caloric effect and its manisfestation in Cu(II)-Ln(III) complexes is described. Molecular nanomagnets containing heterometallic 3d-4f complexes have been investigated extensively for the past few years realizing the role of exchange interaction to minimize the QTM effect. In this context, heterometallic complexes particularly containing CuII-LnIII have encompassed a pivotal role due to the ferromagnetic exchange interaction. Herein we review the Cu/Ln complexes that exhibit single molecule magnet (SMM)/magnetocaloric effect (MCE) in a comprehensive way.
