Hexanuclear lanthanide complexes have been used as molecular precursors to built 3d–4f molecular chains. These complexes were originally targeted as building blocks for the synthesis of lanthanides-containing coordination polymers but reacting them with the 3d molecular precursor [Cu(opba)]2− lead to Ln(III)–Cu(II) hetero-bimetallic chains with general formula [Ln(NO3)(DMSO)2Cu(opba)(DMSO)2]∞ with Ln = Gd–Er. The reaction mechanism can be explained by a sterically-induced reaction where the attack of the [Cu(opba)]2− moiety is driven by the hexanuclear lanthanide clusters geometry. Static magnetic properties of the Gd- and Dy-based chains have been investigated as well as the dynamic magnetic properties of the Dy-containing compound. These studies confirmed that this chemical strategy can possibly yield to 3d–4f single chain magnets.
