混合价三核锰配合物Mn3O(O2CCCl3)6(py)2(H2O)的合成、晶体结构及磁性

摘要

A new mixed-valence trinuclear oxo-centered manganese complex Mn3 (O2CCC13) 6 (py) 2 (H2O) was preparedby the reaction of NnBu4MnO4 with Mn(OAc)2@ 4H2O, trichloroaeetic acid and pyridine in absolute EtOH. Thecrystal structure was determined. The complex crystallizes in monoclinic, space group P21/c, unit cell parameters, a=14.951(1), b=20.791(2), c=17.882(1) A, α=γ=90°, β=102.67(1)°. Variable temperaturesolid state magnetic susceptibility study shows that the complex has an antiferromagnetic exchange interaction.
