5.5 K-Mössbauer spectra of crystalline [Fe9O6]•heptane (top, 0 T) and (tmeda)Fe(OCPh3)2 (bottom, 70 mT). Data are shown in black hash-marks; the red lines are spectral fits with the parameters discussed in the text. Linewidths (FWHM) are 0.33 mm/s for [Fe9O6] and 0.30 mm/s for (tmeda)Fe(OCPh3)2. The maroon arrow in the bottom panel indicates a broad, unidentified impurity accounting for less than 2 % of the total spectral area.
