Synthesis, structure and magnetic property of a new oxo-centered mixed-valent trinuclear manganese complex

Abstract A mixed-valent trinuclear μ 3 -oxo bridged manganese complex [Mn 3 O(O 2 CCH 2 Cl) 6 (Py) 2 (H 2 O)]·0.5C 5 H 5 N was synthesized. Its crystal structure was determined, together with the results of variable temperature magnetic susceptibility, cyclic voltammogram and IR spectrum.
