Fourier-transformed Fe K-edge EXAFS data obtained at 10 K of 3 mM 2b in frozen CH3CN solution with 100 mM PF6 electrolyte. (Inset) k3χ′(k) data. Fourier-transform range k = 2–14 Å−1; experimental data (dotted line) and best fit [solid line; consisting of 2 O/N at 1.77 Å (Δσ2, 0.0028), 4 N/O at 1.97 Å (0.0027), 1 Fe at 2.73 Å (0.0007), and 6 C at 2.93 Å (0.0044)].
