Homo- (4f, 4f) and heterodimetallic (4f, 4f') complexes. The first structurally characterized example of a heterodimetallic (Yb, La) complex (1'). Magnetic properties of 1' and of a homodinuclear (Gd, Gd) analogue

The first structurally characterized example of a heterodimetallic lanthanide complex is presented. The synthetic route involves a tripodal ligand with imine linkers, which offers 10 potential coordination sites all employed to encapsulate two identical or different lanthanide ions. The tripodal ligand is also capable to support a magnetic interaction between the two lanthanide ions. The approach proves to be a general route for preparing homo- and heterodinuclear complexes.
