Phase transition, ferroelasticity and ferroelectricity in Li3InF6

Influence of temperature on disorder of a coordinated dimethylsulfoxide molecule

“…Partial occupation of tetrahedral sites leads to another disorder. The observed antiparallels displacements of atoms from the octahedron centers, are consistent with an antiferroelectric behaviour studied elsewhere [1]. Further researchs are in progress about the electrical properties of the ternary indium fluoride (conductivity) in order to establish the relationship between the mobility of Li + cations and structural characteristics.…”

“…[1] Halasz I., Mestrovic E., Horvat M., Biljan T., submitted [2] The ternary lithium indium fluoride, Li 3 InF 6 , has been found to undergo three allotropic a, b, g forms [1]. Evidence of new structural characteristics occurred, due to the larger trivalent cation size, compared with the Li 3 MF 6 (M=Al, V) compounds.…”

“…In the dimethylsulphoxide adduct of bis (1,3-diphenyl-1,3-propanedion)cadmium(II) complex the two dmso molecules are ligated to cadmium(II) ion through oxygen atoms in cis geometry [1]. Electronic density of one of the two dmso molecules was modeled assuming positional disorder of that molecule over two positions.…”

α-Li3InF6, a ternary fluoride lithium with a new structure type

“…The disordered dmso molecule is situated in a cavity between two phenyl rings which are leaving enough space for the orientation to change without significant energy increase. The ternary lithium indium fluoride, Li 3 InF 6 , has been found to undergo three allotropic a, b, g forms [1]. Evidence of new structural characteristics occurred, due to the larger trivalent cation size, compared with the Li 3 MF 6 (M=Al, V) compounds.…”
