Abstract

Nickel(II)-gadolinium(III), (NiGd(dhbabza)(NO₃)(H₂O)), and copper(II)-gadolinium(III), (CuGd(dhbabza)(NO₃)(H₂O)₃), complexes of a dinucleating ligand, H₄dhbabza, were synthesized and characterized, and their magnetic properties were investigated, where H₄dhbabza denotes N,N′-bis(3-hydroxysalicyli-dene)-2-aminobenzylamine. Cryomagnetic measurements revealed that the intermolecular antiferromagnetic interaction is operating in the Ni(II)-Gd(III) complex, whereas the ferromagnetic spin-spin interaction is operating between Cu(II) and Gd(III) ions in the Cu(II)-Gd(III) complex.
