Powder X-ray Diffraction: PXRD patterns were collected with a PANalytical X'Pert PRO MPD q/q powder diffractometer of 240 millimetres of radius (CuKα radiation; = 1.5418 Å) equipped with a PIXcel detector, in a configuration of convergent beam with a focalizing mirror and a transmission geometry with flat samples sandwiched between low absorbing films (polyester mylar of 3.6 microns of thickness). PXRD measurements were collected on flocculated samples in ethanol with a step size of 0.0263º and a measuring time of 200 seconds per step. Pawley refinements were performed using GSAS-II software. Thermogravimetry: Thermogravimetric Analysis (TGA) was performed on a Mettler-Toledo TGA-851e thermobalance. The experimental conditions required alumina crucibles of 70 μL volume, and an atmosphere of dry nitrogen with 50 mL/min flow rate. A pretreatment of the samples includes a heating step from 30 ºC to 120 ºC at a rate of 10 ºC min -1 , an isothermic step at 120 ºC during 150 min, a cooling step from 120 ºC to 30 ºC at a rate of 10 ºC min -1 and an isothermic step at 30 ºC during 5 min. The final heating step of the samples involves a 10 ºC min ramp rate from 30 ºC to 800 ºC. Elemental Analysis: Elemental analyses were conducted using an EA-1108 elemental analyzer with NCHS configuration.
