Interplay between spin crossover and exchange interaction in iron(III) complexes

Popis výsledku v původním jazyce

In the dinuclear and polynuclear metal complexes exhibiting the low-spin (LS) to high-spin (HS) transition, the spin-crossover phenomenon interferes with the magnetic exchange interaction. The latter manifests itself in forming spin-multiplets, which causes a possible overlap of the band originating in different reference spin states (ILL, LH, HL, and HH). A series of dinuclear Fe(III) complexes has been prepared; the iron centers are linked by a bidentate bridge (CN-, and diamagnetic metallacyanates {Fe(CN)(5)(NO)}, {Ni(CN)(4)} {Pt(CN)(4)}, and {Ag(CN)(2)}). Magnetic measurements confirm that the spin crossover proceeds on the thermal propagation. This information has been completed also by the Mossbauer spectral (MS) data. A theoretical model has been developed that allows a simultaneous fitting of all available experimental data (magnetic susceptibility, magnetization, HS mole fraction) on a common set of parameters.
