Abstract

A novel star-shaped high-spin Fe(III) tetranuclear cluster was unexpectedly obtained by the reaction of an [Fe<sup>III</sup>(phsal)<inf>2</inf>]<sup>-</sup> anion with an Fe(II) coordination cation (H<inf>2</inf>phsal: N-(2- hydroxyphenyl)salicylaldimine). Despite a star-shaped Fe(III) tetranuclear structure similar to reported Fe(III) single molecule magnets, the present compound exhibited a bulk antiferromagnetic transition at 0.6K due to a magnetic exchange coupling through intercluster π-stacking interactions.
