To further investigate the structure of these materials, synchrotron X-ray total scattering measurements were collected at the I15-1 beamline at the Diamond Light Source (see Supplementary Material). The total scattering structure factors, S(Q), of all the materials were processed to account for absorption and various scattering corrections using the GudrunX software. The S(Q) of the 50(Na2O)-50(P2O5) glass is consistent with the observed PXRD pattern (Fig. ). As expected, Bragg peaks are only observed in the S(Q) from samples that include crystalline ZIF-8 material (Fig. ). Pair distribution functions (PDFs) were produced by Fourier transform of the S(Q) data. Here we use the D(r) function in order to accentuate high r correlations. According to calculated total and partial PDFs of Na3P3O9 (Fig. ), the inorganic glass D(r) contains three major correlations at 1.54, 2.47 and 3.43 Å, associated with P-O, Na-O and Na•••P correlations, respectively (Fig. ). The D(r) pattern of ZIF-8 shows characteristics correlations previously described in the literature (Fig. ).
