The FAPBI3 CIF file is significant because it provides a standardized way of representing the crystal structure of FAPBI3, facilitating the sharing and comparison of data among researchers. The file enables researchers to access and analyze the crystal structure data, which is essential for understanding the material's properties and behavior. Furthermore, the FAPBI3 CIF file serves as a reference point for future studies on FAPBI3 and related materials, promoting reproducibility and consistency in research.
: Provides computed and experimental data for the cubic and hexagonal phases.
Many research groups host their specific DFT-relaxed structures on platforms like WMD-group Hybrid Perovskites on GitHub , which provides the raw fractional coordinates for cubic FAPbI
Formamidinium lead iodide ( cap F cap A cap P b cap I sub 3 ) is a widely studied hybrid halide perovskite for high-efficiency solar cells. A CIF (Crystallographic Information File) for cap F cap A cap P b cap I sub 3 fapbi3 cif file
While chemically intuitive, this model assumes the FA cation is spherical and statically centered. In reality, FA is a planar molecule. Fitting diffraction data to $Pm\bar3m$ often results in anomalously high thermal parameters ($B_iso$ or $U_iso$) for the nitrogen and carbon atoms, indicating static disorder rather than true vibration.
CIF file contains the exact spatial coordinates, lattice parameters, and symmetry operations that define the material's atomic structure.

Note: FA+ is often modeled with partial occupancy or split positions to reflect orientational disorder.
If you are looking to simulate or visualize these structures, downloading a reliable FAPbI3.cif from a database like GitHub or the Materials Project is the necessary first step.
