Spin transition in a triazine-based Fe(ii) complex: variable-temperature structural, thermal, magnetic and spectroscopic studies

Author affiliations

Abstract

The crystal structure of a new monomeric Fe(II) spin-crossover thiocyanate complex with a polypyridyl triazine-based ligand is reported at three temperatures. Spectroscopic, thermal and magnetic studies are presented that allowed the characterization of the thermal spin-crossover experienced by this compound and its cooperative character. The temperature of the transition is close to 200 K and the process is characterized by thermodynamic variations of ΔtrsH = 7.22(2) kJ mol−1 and ΔtrsS = 36.4(2) J mol−1 K−1.
