K for hrs to remove pore content. The X-ray powder diffraction (XRPD) pattern was collected at room temperature on a STOE Stadi-P diffractometer with Cu-Kα 1 radiation (λ " 1.540596 Å), a Ge( ) Johann monochromator, and a DECTRIS Mythen K detector in Debye-Scherrer geometry over an angular range of -. ˝ θ with a step size of . ˝and s count time per step. Activated powder was loaded into a . mm borosilicate glass capillary, flame-sealed to minimize further moisture uptake, and spun during the measurement to improve the crystallite orientation sampling statistics.
