A three-spin complex [Ni(salox)2(IM4Py)2] containing salicylaldoxime and nitronyl nitroxide: Structure and magnetic properties

A transition metal-radical heterospin complex [Ni(salox)2(IM4Py)2] (1) (salox = salicylaldoxime, IM4Py = 2-(4′-pyridinyl)-4,4,5,5-tetramethylimidazoline-l-oxyl) (1) has been synthesized based on the substitution reaction of Ni(salox)2(py)2 and IM4Py. Compound 1 exhibits a chain structure created by the intermolecular hydrogen bonds. Magnetic measurements show intermolecular antiferromagnetic interactions in 1.
