Crystal structure, vibrational and optical properties of N-(3-ammoniumpropyl)-1,3 diammoniumpropane hexabromobismuthate monohydrate: [C6H20N3]BiBr6 H2O

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

“…It can be clearly seen that the band gap energies of zero-dimensional isolated octahedron takes place at a higher energy (E g ¼ 2.78 eV) in (C 6 H 20 N 3 )BiI 6 $H 2 O and (E g ¼ 2.90 eV) in (CH 3 NH 3 ) 3 Bi 2 I 9 [29] than those of the corresponding octahedra which may share corners, edges or faces (C 10 H 7 NH 3 )BiI 4 (E g ¼ 2.32) [31] and (C 6 H 18 N 2 )BiI 5 (E g ¼ 2.48 eV) [37]. Besides, the band gap energies occurs at substantially weaker energy compared to those found in the homologous bromide compound which has the same organic molecules as our (C 6 H 20 N 3 )BiBr 6 $H 2 O (E g ¼ 3.10 eV) [9].…”

Synthesis, crystal structure, spectroscopic characterization and optical properties of bis(4-acetylanilinium) tetrachlorocobalt (II)

“…Spectroscopic studies of organic-inorganic hybrid compounds have been reported in the literature from time to time [15][16][17]. In fact, vibrational spectroscopy is an efficient tool for obtaining information about structural and electronic features of molecules [18][19].…”

Synthesis, crystal structure and Hirshfeld surface analysis of a polymeric bismuthate(III) halide complex, (C6H6N3)2[BiCl5]·2H2O

“…polynuclear) inorganic networks of corner-, edge-, or face-sharing octahedra, leading to an extensive family of bismuth halogenoanions (Jakubas, 1986;Jakubas et al, 1988Jakubas et al, , 1995. A variety of organic cations, ring shaped or linear, have a strong impact on the arrangements of BiX 6 octahedra and the formation of hydrogen bonds (Dammak et al, 2015;Elfaleh & Kamoun, 2014). This class of compounds has also attracted much attention in the field of crystal engineering over the last decade on account of their capability for the creation of extended architectures via intermolecular non-covalent binding interactions.…”
