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

摘要

Nickel(II)-gadolinium(III), (NiGd(dhbabza)(NO3(H2O)), and copper(II)-gadolinium(III), (CuGd(dhbabza)(NO3(H2O)(3)), complexes of a dinucleating ligand, H(4)dhbabza, were synthesized and characterized, and their magnetic properties were investigated, where H(4)dhbabza denotes N,N'-bis(3-hydroxysalicylidene)-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.
