Abstract

A new Mn^III/Mn^II 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.
