Mixed-valent trinuclear manganese complex with N,N’-bis(2-hydroxy-3,5-dimethylbenzyl- N,N’-dimethyl-1,2-ethanediamine (H2hdde), [Mn3(hdde)2(CH3CO2)2(CH3O)2], was synthesized. The X-ray crystal structure analysis revealed that compound is a trinuclear manganese complex with linearly arrangement of MnIII-MnII-MnIII, where two manganese ions of each MnII-MnIII pair are bridged by μ-phenolato-oxygen of hdde2– ligand, μ-methanolato-oxygen, and μ-acetato ion. Temperature dependence of magnetic susceptibilities showed an increase of magnetic moment as the temperature lowers in the range of 300—6 K and a decrease below 6 K. The magnetic analysis based on Heisenberg model yielded ferromagnetic coupling (J = 2.62 cm–1) between MnIII and MnII ions |
