Abstract

Abstract: A four-spin complex {[Mn(hfac)2]2(4P4NIT)2}·CHCl3(4P4NIT=2-(4′-(4″-pyridyl)phenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide, hfac=1,1,1,5,5,5-hexafluoro-acetylaceonate anion) was synthesized using a pyridyl substituted nitroxide radical. The single crystal X-ray analysis reveals that two 4P4NIT radicals act as bridging ligand linking two Mn(hfac)2 units together. The magnetic study shows that there exists strong magnetic interaction between Mn(Ⅱ) ions and directly bonded radicals.

Key words: nitronyl nitroxide radical, Mn(Ⅱ), crystal structure, magnetic properties
