“…Unlike the normal situation in iron(II) and also in many other iron(III) systems, 57 Fe Mössbauer spectroscopy generally fails to give clear evidence of the simultaneous existence of the two electronic states. The 57 Fe Mössbauer spectra of the dithiocarbamate systems exhibit only a single quadrupole doublet with broad line widths within the temperature range of the spin crossover [35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50]. The rapid inter-conversion of spin states-faster or comparable to the lifetime of the 57 Fe nucleus (t=1.410 7 s)-in those materials prevents the observation of separate lines for high spin and low spin molecules.…”

In this chapter, selected results obtained so far on Fe(III) spin crossover compounds are summarized and discussed. Fe(III) spin transition materials of ligands containing chalcogen donor atoms are considered with emphasis on those of N,N-disubstituted-dithiocarbamates, N,N-disubstituted-XY-carbamates (XY=SO, SSe, SeSe), X-xanthates (X=O, S), monothio-b-diketonates and X-semicarbazones (X=S, Se). In addition, attention is directed to Fe(III) spin crossover systems of multidentate Schiff base-type ligands. Examples of spin inter-conversion in Fe(III) compounds induced by light irradiation are given.
