The results are cross-compared to the corresponding data obtained from the recently published measurements with Mn-based SMM [1], also in terms of the local spin and orbital, magnetic moments obtained. Furthermore, [Fe(III)16cr(III)](3+)single crystals have been experimentally studied by means of magnetometry and X-ray diffraction. |
