Dear Rietvelder, I was just trying to do quantitative and qualitative rietveld refinement of Powder XRD patterns (employing TOPAS software) of various phases originated from the decomposition of CH3NH3PbI3 perovskite.
Though recent work from Yixin Ren et. al. Cryst. Growth Des. 2016, 16, 2945?2951 from Univ. Texas at Dallas was quiet excellent, but still I need assistance in finding the exact following .cif files of following "Bold" phases. The literature propose that "CH3NH3PbI3" perovskite decomposes first into "CH3NH3I" solution and "PbI2" in the presence of H2O. The "CH3NH3I" then decomposed into "CH3NH2" and HI later react with O2 or decompose under illumination into H2 and I2. Does any body know any link to the said .cif--repository. Unfortunately currently, I don't have access to crystallographic databases. If any-Rietvelder is also in this business, please reply. Best Regards, Dr. Naveed Zafar Ali
