Full structure refinement of a spectrum recorded during laser heating at 2125 (70) K under a pressure of 44.6 GPa. We obtained a very good agreement of the spectral intensities [Rwp = 1.11% and R(F2) = 5.7% for the iron phase] using an orthorhombic cell [a = 2.3460 (3), b = 4.1445 (5), c = 4.0615 (8) Å], space group Pbcm (57), and iron location at (0.239, 0.472, 0.25). Displayed are the observed, calculated and difference spectra. The Fe pattern (lower ticks) is associated with reflections from the Al2O3 pressure-transmitting medium (upper ticks).
