In this work the crystal structure by single crystal X‐ray measurement and optical properties of 1D propane‐1,2‐diammonium pentachlorobismuthate [NH 3 CH 2 CH(NH 3 )CH 3 ]BiCl 5 organic–inorganic hybrid perovskite are presented. It is prepared by mixing ethanolic solution of equimolar ratios (1:1) of its basic components. The title compound crystallized in the noncentrosymmetric orthorhombic space group Pca 2 1 with Z = 8 molecules per unit cell. The unit‐cell parameters are a = 19.8403 (7) Å, b = 6.3303 (2) Å, c = 19.0314 (7) Å. The vibrational spectra are studied by Raman and infrared spectroscopy. The optical properties show a strong absorption in the ultraviolet region, the band gap energy E g is found to be 3.15 eV. Cathodoluminescence measurements are also discussed.
