【 摘 要 】

A new mononuclear gadolinium complex: [Gd(tfac)3(NIT-2thz)] (tfac = trifluoroacetylacetonate; NIT-2thz = 2-(2′-thiazolyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide) was synthesized, structurally and magnetically characterized. Single-crystal X-ray structural analysis reveals that this complex crystallized in the C2/c space groups. Each central Gd ion is eight-coordinated by three bischelate tfac ligands and one radical ligand. Through magnetic study, ferromagnetic Gd (III)-radical coupling of this complex were observed.
