Extended Data Fig. 1

a, High-angle annular dark field (HAADF) image (a, top left) and energy-dispersive X-ray spectroscopy (EDS) Zr (a, top right; yellow), Ni (a, bottom left; green) and Br (a, bottom right; red) mapping of a microcrystalline powder sample of 1(NiBr2)15. b, STEM-EDS line scan analysis for Ni (red) 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 72 ± 12% for Ni and 28 ± 12% for Zr, corresponding to a Ni:Zr ratio of 2.6. c, EDS spectrum for the crystallite of 1(NiBr2)15. Signals for Cu and Au originate from the space-filling washer and sample grid, respectively.
