A dinuclear gadolinium complex based on schiff base ligand: structure and magnetic properties

A novel dinuclear dysprosium complex, namely [Gd-2 (L) 4 (C2H3O2)(2) (CH3OH)(2)] (1) (L= 2-hydroxy-3-methodxybenzaldehyde-5-bromo oxime), was synthesized, structurally and magnetically characterized. Single-crystal X-ray structural analysis reveals that complex 1 is neutral dinuclear complex, in which two Gd (III) ions with nine-coordinated environment are bridged by two phenoxide groups from two Schiff base ligands and four O ions from two molecules of methanoic acid. The magnetic study of complex 1 indicates the slow relaxation of magnetization.
