Comment: This is the experimentally resolved structure, which contains a statistical (disordered) representation of the equatorial iodine atoms in the original refinement. This structure is our recommended "best" published experimental structure for phenethylammonium lead iodide at room temperature, supported by a computational comparison of the total energies of various published structures after full structure optimization in Chemistry of Materials, Vol. 34, issue 7, 3109-3122 (2022), https://doi.org/10.1021/acs.chemmater.1c04213. The computationally relaxed (PEA)2PbI4 structure with resolved disorder (i.e., no overlapping iodine positions), optimized using the PBE+Tkatchenko-Scheffler approach, is also available in the HybriD3 database (see datasets linked to the present one.)
