Originální abstrakt

We crystallized the Schiff-base iron(III) spin-crossover complex [Fe(3,5Cl-L5)(NCSe)] from different two-component solvent mixtures containing methanol and chloroform (phi = V(CH3OH)/V(solvent) = 0.05, 0.25, 0.50, 0.83, and 1.00). The obtained crystalline products were characterized by X-ray diffraction, and it was confirmed that they are all composed of the same crystalline phase, and they do not contain any crystal solvent. However, significant differences in magnetic properties were observed, and thermal hysteresis changed from (in K) 121T down arrow and 134T up arrow for phi = 0.05 and 0.25, down to 72T down arrow and 96T up arrow for phi = 1.00. The crystal structures of the low-spin and high-spin phases were studied theoretically and experimentally.
