Parallel-mode X-band EPR spectra of (A) Fe(TPP)(2-MeHIm)], powder; (B) [Fe(TPP)(2-MeHIm)]2·2-MeHIm, powder; K(222)[Fe(TPP)(2-MeIm−)], 6 mM in chlorobenzene (C) and powder (D); K(222)[Fe(OEP)(2-MeIm−)], 6 mM in chlorobenzene (E) and powder (F). Experimental conditions: temperature 2 K; microwave power, 0.02 mW at 9.3(1) GHz. Simulation parameters (F, dashed line): S = 2, D = −8cm−1, E/D = 0.10, σ(E/D) = 0.02, gz = 2.26.
