*3.3. X-Ray Powder Di*ff*ractometry (XRPD)*

XRPD of the samples was collected at room temperature (25.0 ± 2.0 ◦C) on a Bruker D8 Advance Di ffractometer (Bruker, AXS, Karlsruhe, Germany). The instrument was operating with Cu K α radiation (1.54 Å) passing through a nickel filter, and the tube voltage was set at 40.0 kV and current of the generator (amperage) at 40.0 mA. The sample (250-300 mg) was mounted on a poly(methyl methacrylate) (PMMA) sample holder and pressed with a glass slide to achieve coplanarity with the surface of sample holder. Each sample was then scanned in 2θ range of 5.0◦-40.0◦ with a step size of 0.05◦ and a step time of 1.0 s. The obtained data were plotted using OriginPro software (OriginLab Corporation, Northampton, MA, USA).
