Extended Data Fig. 5: Comparison of Ni(ii) site occupancies.
From: Confinement of atomically defined metal halide sheets in a metal–organic framework

a, b, Nickel site occupancies for single-crystal structures of NiBr2-loaded (a, light to dark red) and NiCl2-loaded (b, light to dark green) 1 obtained by reaction of 1 with 1.00 equiv to excess (>50 equiv) NiX2 (X = Br, Cl) in diglyme. Error bars represent the crystallographic standard uncertainties of the Ni(ii) site occupancies. Lines are included to guide the eye.
