Thermally and Light-Induced Spin-Crossover in Iron(III) Complexes with Benzophenone-Based Saltrien Ligands: Hysteresis, Two-Step Transitions, and the LIESST Effect.

ABSTRACT: The synthesis and characterization of four new iron(III) coordination compounds with saltrien-like hexadentate Schiff base ligands L_n, prepared by condensation between triethylenetetramine and 2-hydroxy-3,5-dimethylbenzophenone (L₁, C1-C3) or 2-hydroxy-5-methoxybenzophenone (L₂, C4), are reported. The complexes [Fe(L_n)]X·mCH₃CN (X = SeCN^- for C1 and C4, SCN^- for C2 and BPh₄^- for C3, m = 0 for C3, m = 1 for C1 and C4, m = 2 for C2) were structurally characterized, and their spin-crossover (SCO) was monitored by magnetic measurements, X-ray powder diffraction analysis, and EPR
