Total scattering data were acquired at beamline 28-ID-1 of the National Synchrotron Light Source II (λ = 0.1665 Å) at room temperature. The powder samples were packed and flame-sealed under a vacuum in borosilicate capillaries (outer diameter: 1.4 mm; inner diameter: 1.2 mm). The diffraction data, collected with an X-ray wavelength of 0.1665 Å and a sample-to-detector distance of ≈ 217.7965 mm, allowed for a usable Q max = 26 Å-1 . The experiment employed a wide-angle X-ray PerkinElmer image plate detector (2048×2048 array, 200 µm pixel pitch). Two images were collected and averaged for each sample, each with a total sample exposure time of 60 s, detector exposure time of 0.5 s, and sleep time of 60 s. CeO 2 (SRM674b) was used to calibrate the detector position and alignment. Data normalization into S(Q) and transformation into the pair distribution function,
