Spectroscopic and structural characterization of Fe(Ph)Br(SciOPP) (5-Br). (A and B) The 80 K Mössbauer and (C and D) 5 K, 7T NIR MCD spectra of the in situ iron species from reaction of 1-Br2 with 1 equiv PhMgBr for 3 min at 0 °C in (A and C) 1:1 THF/2-MeTHF and (B and D) 1:1 Et2O/isopentane. Saturation magnetization data (dots) and best fit (lines) collected at 6100 cm–1 (C, inset) and 6120 cm–1 (D, inset). (E) X-ray crystal structure of 5-Br with thermal ellipsoids shown at 50% probability. The individual Mössbauer components are identified as 5-Br (green), 4a (red), and 1-Br2 (beige).
