摘要: One new MnII2MnIII6 cluster exhibiting an S = 17 spin ground state and single-molecule-magnet properties has been designed linking MnIII3-salicylaldoximate triangles tetracoordinated MnII cations by means of end-on azido bridges. The ferromagnetic coupling rationalized as a function their structural parameters.
