Crystal structure, vibrational and optical properties of a new self-organized material containing iodide anions of bismuth(III), [C6H4(NH3)2]2Bi2I10·4H2O

Structural characterization, vibrational studies and optical properties of a new luminescent organic-inorganic material [C6H20N3]BiI6·H2O

“…The absorption peaks found in the absorption spectrum are very similar to those observed in other organice inorganic hybrid materials containing [BiI 6 ] 3À anions described in literature [7,24,25]. The absorption peak at 2.78 eV is consigned to an electronic transition between the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) [31,32], while the second absorption band at 2.27 eV is due to the exciton created in the inorganic [BiI 6 ] 3À anions [33].…”

Synthesis, Crystal Structure, and Characterization of a New Organic-Inorganic Hybrid Material:

“…The size of the organic cations, their symmetry, and ability to form the hydrogen bonds determine the physical properties in these materials (e.g., nonlinear optical properties, luminescence, conductivity etc.) [2][3][4][5][6]. The halobismuthate (III) family, in particular the chlorobismuthate, is composed of distorted (BiCl 6 ) 3− isolated octahedra or connected by corners, edges, or faces forming ribbons, plans, or layers.…”

Crystal structure, thermal studies, Hirshfeld surface analysis, vibrational and DFT investigation of organic-inorganic hybrid compound [C 9 H 6 NOBr 2 ] 2 CuBr 4 ·2H 2 O

“…5 and 6 show the experimental and calculated I.R and Raman spectra, respectively. Furthermore, in Table 5 The lowest energy absorption peak at 300 nm (4.13 eV) is due to band gap absorption and it is assigned to the excitation of free electron-hole pairs within the [CuBr 4 ] 2-inorganic chain [29,30].…”
