The total scattering data obtained from X-ray synchrotron diffraction measurements were normalised to produce the structure factors, S(Q), of the parent glasses (Figure ) and the blends (Figure ). The associated PDFs were obtained by Fourier transforming these structure factors. The obtained PDF for agZIF-62 is consistent with literature PDFs of agZIF-62 and contained short-range (< 6 Å) peaks at interatomic distances corresponding to those within the imidazolate ring of the linkers and the local Zn environment (A-E) present in the crystal structure of ZIF-62 (Figure ). Assigning peaks to the inorganic glass (IG) is more challenging given the lack of a crystalline analogue to which bond lengths could be compared. Nonetheless, the main correlations P-O, P-Na and Na-O were identified by comparing the PDF peaks to bond distances in the Na3P3O9 phase that sodium ultraphosphate glasses can recrystallise to, in addition to those obtained from other scattering experiments (Figure ). Importantly, comparing PDFs of the starting materials before and after heating indicate no structural changes of either component glass resulting from the thermal treatment (Figure ).
