Abstract

A systematic study of a series of Fe(II) complexes with the tetradentate N2S2-binding ligand and NCX− coligands (X = S, Se, BH3) conclusively demonstrates the occurrence of temperature-driven spin crossover (SCO), which is rarely observed for the Fe(II) ion in the N4S2 coordination environment. The SCO is confirmed by crystallography, magnetic measurements, and Mössbauer spectroscopy. The last two methods also reveal a light-induced excited spin state trapping (LIESST) effect at low temperatures.
