Abstract

Three Salen-like gadolinium complexes, namely, mononuclear (4f) complex [{H₂L}Gd(NO₃)₃] (1), heterodinuclear (3d-4f) complex [{LCu}Gd(NO₃)₃]·0.25H₂O (2) and dimeric heterotrinuclear (3d-4f-3d′) complex [{LCu}Gd(H₂O)₃{Fe(CN)₆}]₂·6H₂O (3) [H₂L = N,N′-ethylene-bis(3-methoxysalicylideneimine)] have been synthesized by stepwise reactions. X-ray diffraction analysis reveals that 1 is of a discrete structure in which H₂L coordinates to gadolinium ion through O₂O₂ moiety. Then, addition of Cu(Ac)₂·H₂O to the mononuclear lanthanide complex yields expected heterodinuclear (3d-4f) complexes [{LCu}Gd(NO₃)₃]. 3 features a unique 1D ladder-like topology structure through the intermolecular double links of Cu-N bonds. The measurement of variable-temperature magnetic susceptibility reveals that complex 1 exhibits antiferromagnetic interaction while 2 and 3 exhibit ferromagnetic interaction between spin carriers. The correlations between the structure and magnetism are described and discussed.
