Solvothermal indium fluoride chemistry: Syntheses and crystal structures of K5In3F14, β-(NH4)3InF6 and [NH4]3[C6H21N4]2[In4F21]

115In and 19F MAS NMR study of (NH4)3InF6 phases

“…This result is inconsistent with the assumed tetragonal symmetry of this phase, requiring at least one twofold disordered ammonium ion. Another transition is observed at 230 K. The final symmetry at very low temperature is announced to be triclinic for all ammonium elpasolites [9], however, a monoclinic structure of (NH 4 ) 3 InF 6 at 113 K has been reported recently [10].…”

Solvothermal and hydrothermal processes: the main physico-chemical factors involved and new trends

“…-with a particular composition (for example the extension from oxides systems to fluorides [132], sulphides [133,134], sulphate-fluorides [135], nitrides [136,137], hybrids [138], carbon-systems [139], metallic systems [140], metalorganic frameworks [141], etc. ); -with the synthesis of specific structures, such as perovskite or pyrochlore, in mild conditions [142]; -with some specific characteristics in size but mainly in morphology such as nanotubes [127], fibrous systems [143], nano-composites [144]; -with a specific application (as nanophosphors) [145,146], -nano-composites associating different classes of materials (such as carbon and oxides) [147].…”

Synthesis, Crystal Structures and Characterization of Two Nonmetal Cation Tetrafluoroborates

“…Hybrid materials can be classified according to the dimensionality of the network. The dimensionality of the network can be 0D formed by isolated polyanions [1], one dimensional (1D) chains [2], two-dimensional (2D) formed by layers [3,4], and three-dimensional (3D) [5]. The cohesion between organic and inorganic moieties are provided by weak forces (hydrogen bonding and Van der Waals forces) or strong forces (covalent bonds).…”
