To confirm the presence of mixed organic-halide linkers in the modified ZIF glasses, we have performed in situ high temperature X-ray pair distribution function (PDF) measurements of the three crystalline ZIFs mixed with the imidazolium-based halide salts (Cl -, Br -, I -). An example of the recorded pair distribution function, G(r), data is shown in Fig. for the ZIF-62-bImCl (R=0.5)
