摘要：
The reaction of manganese halides with polydentate Schiff bases obtained by the condensation of 3-ethoxysalicylaldehyde and different amino alcohols, resulting in a NO3 set of donors, yielded a series of manganese clusters with {MnIII6MnIINa2}, {MnIII3MnIINa}, and {MnIII3} metallic cores. The influence of the ligand substituents and the halide on the final nuclearity has been studied. Analysis of their static magnetic behaviour confirms the ground states of 19/2 for the {MnIII6MnIINa2} complexes, 7/2 for the {MnIII3MnIINa} clusters, and 12/2 for the triangular {MnIII3} systems, and a weak field induced a slow relaxation of the magnetization for the trinuclear complexes.
