A series of the rare earth-copper heteronuclear complexes R 2 Cu 3 (HBen) 3 .6H 2 O.4DMF (HBenH 4 =N,N'-bis-(o-hydroxybenzoyl)ethylenediamine; R = Y, Pr-Yb) have been synthesized and characterized by element and thermal analyses. The magnetization M vs. magnetic field H curves of these complexes have been measured at 1.5 K, which all show ferromagnetic character...
