In this work the crystal structure by single crystal X‐ray measurement and optical properties of 1D propane‐1,2‐diammonium pentachlorobismuthate [NH3CH2CH(NH3)CH3]BiCl5 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 Pca21 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 Eg is found to be 3.15 eV. Cathodoluminescence measurements are also discussed.
Organic–inorganic hybrid perovskites (OIHs) are exceptionally promising sector of novel materials for optoelectronic applications. Herein, the OIHs of the formula [(NH3)2(CH2)3]CuCl4 labeled by C3CuCl and [(NH3)2(CH2)4]CuCl2Br2 labeled by C4CuClBr are prepared by slow evaporation method. The synthesis process is achieved by mixing equimolar ethanolic solutions ratios (1:1) of their basic components (organic/inorganic). Characterizations of these materials using microchemical analysis, energy dispersion X‐ray (EDX) and X‐ray diffraction (XRD) are discussed. The XRD is used to estimate the crystalline size for prepared compounds and found in the range of 38.8 and 48.8 nm for C3CuCl and C4CuClBr, respectively. The vibrational spectra are studied by Fourier transformation infrared spectroscopy (FTIR) and show the major diffraction peaks of compounds and their assignment. UV‐region strong absorption is clarified in the optical properties studied for Cu hybrid, whereas the bandgap energy estimated via Kubelka–Munk equation and found 2.8 and 3.85 eV for C3CuCl and C4CuClBr, respectively.
In the pages that follow,the structure of the crystal, unit cell dimension and complete structure information will be shown by single crystal x-ray diffraction and measuring some physical properties of 1D propylene diammonium pentachloro bismuthate [(NH3)2(CH2)3]BiCl5 organic-inorganic hybrid perovskites (OIHs).Slow evaporation method is used to prepared the synthesis. The process of preparation occurred by mixing ethanolic solution of equimolar ratios (1:1) of its basic components (organic / inorganic). The Bi hybrid crystallized in orthorhombic non centro-symetric Pca21 structure with 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 average C-C bond lengths are 1.50Å. The average N-C bond lengths are 1.47Å. The connection between organic parts to inorganic part is via hydrogen bond (H. Bond). Raman spectroscopy and also Fourier transform infrared spectroscopy (FTIR) have been used to study the vibrational spectra that shows the main diffraction peaks and their assignment. Diffuse reflectance spectra (DRS) method is used to study the optical properties and show that there is a strong absorption in the UV region for Bi hybrid. Kubelka–Munk equation has been used to calculate the band gap energy and indicates that the band gap for the present investigated hybrid is equals 3.15 eV.
