Abrupt spin crossover in an iron(iii) quinolylsalicylaldimine complex: structural insights and solvent effects

Abstract

The first Fe(III) qsal-X complex exhibiting abrupt complete spin crossover at 228 K with a hysteresis of 8 K, [Fe(qsal-I)2]OTf is reported. Structural studies of the MeOH solvate in the LS and HS state and at the spin transition are described.
