Synthesis and Magnetic Properties of Nickel(II)-Gadolinium(III) and Copper(II)-Gadolinium(III) Complexes of a Compartmental Ligand, N,N′-Bis(3-Hydroxysalicylidene)-2-Aminobenzylamine

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.
