Structure and phase transitions in chloroantimonate(V) crystals: [(C2H5)3NH]SbCl6 and [(C2H5)3NH]SbCl6·1/2[(C2H5)3NH]Cl

Synthesis, crystal structure, thermal analysis and dielectric properties of [(C4H9)4N]3Bi2Cl9 compound

“…Indeed, the type of anionic form in these hybrids is clearly associated with the size and symmetry of both organic cations and the type of halogen atoms [18,19]. The experimental studies on many halogenometalates based on various alkylammonium cations like ethylammonium [20,21], metylammonium [22,23] and propylammonium have exhibited interesting dynamics of the alkylammonium groups. This behavior proves the important role of the cations in the mechanisms of the phase transitions.…”

“…[Cl-EMIm][SbCl 6 ] crystallizes also monoclinic in the space group P2 1 /c with four formula units in the unit cell. The crystal structure of compound 2 consists of alternating (6) 239.6(1) N(1)ϪC (6) 144.8 (6) Cl (1)ϪSbϪCl (2) 91.4(1) Cl (2)ϪSbϪCl (5) 90.3(1) Cl (1)ϪSbϪCl (3) 89.4 (1) Cl (3)ϪSbϪCl (5) 90.5(1) Cl (2)ϪSbϪCl (3) 90.6(1) Cl (4)ϪSbϪCl (5) 90.5(1) Cl (1)ϪSbϪCl (4) 90.9(1) Cl (1)ϪSbϪCl (6) 89.8(1) Cl (2)ϪSbϪCl (4) 89.8 (1) Cl (2)ϪSbϪCl (6) 178.8(1) Cl (3)ϪSbϪCl (4) 179.5 (1) Cl (3)ϪSbϪCl (6) 89.4(1) Cl (1)ϪSbϪCl (5) 178.3 (1) Cl (4)ϪSbϪCl (6) (2)ϪSbϪCl (4) 89.9(1) Cl (2)ϪSbϪCl (6) 90.2(1) Cl (3)ϪSbϪCl (4) 179.9 (2) Cl (2)ϪSbϪCl (5) 179.7 (2) layers of 1-ethyl-3-methyl-4-chloroimidazolium cations and the hexachloroantimonate(V) anions ( Figure 2 and Table 1).…”

“…Compounds of both types exhibit interesting ferroic (ferroelastic) properties. The mechanism of the relevant phase transitions seems to be complex while both sublattices, cationic and anionic, are involved [2,3]. Therefore, new [SbCl 6 ] Ϫ compounds and their structural characterization are of interest.…”

Synthesis, Crystal Structure, Thermal and Dielectric Properties of a New Semi-organic Crystal: 2[N(2-Aminoethyl)-1,3-propanediaminium] octachlorodimercurate, tetrachloromercurate

“…5. The assignment of the internal modes of the organic cations is based on the comparison with the well-documented spectra of the homologous compounds [17,18]. The IR spectra show, at high wavenumbers, an absorption that is centered at 3,035 cm -1 assignable to m s (NH 3 ?…”
