Structures and phases transition in hexylenediammonium pentachlorobismuthate (III) [NH3(CH2)6NH3]BiCl5 crystal

Raman scattering and alternative current conduction mechanism of the high‐temperature phase transition in [(C4H9)4N]3Bi2Cl9

“…[1][2][3] Among these salts, which are characterized as a wide variety of stoechiometries, [4][5][6] those with the [M 2 X 9 ] 3À and [M 2 X 11 ] 5À compositions that are exhibiting ferroelectric, ferroelastic, and optical properties deserve special attention. [7][8][9] The continuing interest is due not only to their structural diversity but also to their potential applications in information processing and in low-cost electronic devices (thin-film transistor, organic-inorganic emitting diode). [10,11] The anionic [M 2 X 9 ] 3À sublattices are built of distorted [MX 6 ] 3À octahedra connected with each other by edges (one-dimensional zigzag chains), corners (two-dimensional layers), or faces (discrete bioctahedrals).…”

“…X-ray, thermal and vibrational studies of phase transitions have also been performed for highly related compounds belonging to the alkanediammonium halogenobismuthate salts family as the pentachlorobismuthate one (NH 3 (CH 2 ) n NH 3 )BiCl 5 (Jeghnou et al, 2005;Ouasri et al, 2012;Rhandour et al, 2011;Ouasri et al, 2013a;Ouasri et al, 2013b;Ouasri et al, 2014). The aim of the present paper was to study the recently synthesized butanediammonium hexafluorosilicate (NH 3 (CH 2 ) 4 NH 3 )SiF 6 crystal, by X-ray diffraction at room temperature.…”
