Abstrakt: (4NPEA) 2 PbI 4 (4NPEA = 4-nitrophenylethylammonium) is the first 3 × 3 corrugated 2D organic-Pb/I perovskite. The nitro groups are involved in cation-cation and cation-iodide interactions. The structure contains both highly distorted and near-ideal PbI 6 octahedra, consistent with the observation of two 207 Pb NMR resonances, while the optical properties resemble those of other 2D perovskites with distorted PbI 6 octahedra.
