The iron structure in (a) P42212 and (b) P21c. Compare the Fe—Fe vectors, the Fe—C vectors, and the Fe—Li vectors, and recall that the Fourier transform of the diffraction intensities (F2) is the Patterson function, in which peaks are atom-to-atom vectors as opposed to atom positions in the electron-density map.
