Abstract

A new MnIII/MnII tetranuclear complex, [Mn 4(hmp)6(CH3CN)2(H2O) 4](ClO4)4 • 2CH3CN (1) has been synthesized from the reaction of 2-hydroxymethylpyridine (Hhmp) with Mn(ClO4)2 • 6H2O in the presence of tetraethylammonium hydroxide. Structural characterization of 1 by X-ray diffraction on single crystal shows that Mn ions are arranged in a double-cuboidal fashion where Mn2+ are hepta-coordinated and Mn 3+ centers hexa-coordinated. Magnetic properties have been studied and reveal that 1 behaves as a Single-Molecule Magnet (SMM) appearing at the highest temperature known in the Mn4/hmp family.
