Extended Data Fig. 4: High-angle annular dark field images and energy-dispersive spectroscopy data for 1(FeCl2)19.
From: Confinement of atomically defined metal halide sheets in a metal–organic framework
a, High-angle annular dark field (HAADF) image (a, top left) and energy-dispersive X-ray spectroscopy (EDS) mapping Zr (a, top right; yellow), Fe (a, bottom left; orange) and Cl (a, bottom right; green of a microcrystalline powder sample of 1(FeCl2)19. b, STEM-EDS line scan analysis for Fe (orange) and Zr (yellow) across the length of the crystallite plotted as normalized atom per cent. The average amount for the two elements was determined to be 77 ± 9% for Fe and 23 ± 9% for Zr, corresponding to a Fe:Zr ratio of 3.3. c, EDS spectrum for the crystallite of 1(FeCl2)19. Signals for Cu and Au originate from the space-filling washer and sample grid, respectively.
