*2.4. Powder X-ray Diffraction (PXRD)*

PXRD data were collected using a Bruker D8 Advance Series II Vαrio diffractometer (Bruker-AXS, Karlsruhe, Germany) equipped with a LYNXEYE detector and Cu-Kα<sup>1</sup> radiation (1.5406 Å). Diffraction patterns were collected over a 2θ range of 5–60◦ using a continuous step size of 0.02◦ and a total acquisition time of 30 min.
