The reaction of Fe(NO3)2, trz, and atrz in ethanol–water gave solid Fe(trz)3x(atrz)3-3x(NO3)2·H2O(x = 0.1, 0.2, 0.4, 0.8). The solids were investigated by magnetic chemistry, X-ray diffraction, photoelectron (DRS), IR, and Mossbauer spectroscopy methods. The individual Fe(trz)3(NO3)2 and Fe(atrz)3(NO3)2 as well as the solid phases exhibit a reversible spin crossover 1\(^1 A_1 \Leftrightarrow ^5 T_2 \), whose temperature and character depend on the phase composition. Due to this, Tc may be changed by introducing another ligand into the complex exhibiting a spin crossover effect. |
