Structure–property relationships in hybrid (C₃H₅N₂)₃[Sb₂I₉] and (C₃H₅N₂)₃[Bi₂I₉] isomorphs

Abstract

Two hybrid crystals imidazolium iodoantimonate(iii) and iodobismuthate(iii) have been synthesized and characterized in a wide temperature range (100–350 K) by means of X-ray diffraction, dielectric spectroscopy, proton magnetic resonance, FT-IR spectroscopy and optical observations.

Formation and distortion of iodidoantimonates(III): the first isolated [SbI6]3−octahedron

“…The most interesting issues, from the crystal engineering point of view, within mixed inorganic-organic halogenidoantimonates(III) with organic cations are the reasons and rules leading to the formation of different anionic substructures along with an understanding of the distortion of inorganic polyhedra and the correlations between their structures and properties (Desiraju et al, 2011;Mitzi, 1999;Saparov & Mitzi, 2016;Bujak et al, 2000;Owczarek et al, 2013;Sghaier et al, 2014;Bujak, 2015b;Wojtaś et al, 2016;Wę cławik et al, 2016). Although significant progress has been achieved, the formation of particular anionic substructures that is determined by the differences in size, symmetry and the ability to form hydrogen bonds with organic cations and the appropriate halogen atoms still remains a challenge (Bujak & Zaleski, 2004).…”

Structure, ferroelasticity and Goldilocks zone phase transitions in C3H5N2Al(SO4)2·6H2O

“…In recent years, crystals have been found containing ring-shaped cations, i.e. imidazolium and pyrrolidinium, that showed ferroic phase transitions including ferroelasticity and ferroelectricity (Piecha et al, 2012;Czapla et al, 2015;Zhang, Shao et al, 2015;Wę cławik et al, 2016;Rok et al, 2020;Ksią dzyna et al, 2019;Zhang et al, 2015aZhang et al, ,b, 2016. We decided to check the possibility of obtaining such an aluminium compound containing imidazolium cations with a formula of…”

Exploring a lead-free organic–inorganic semiconducting hybrid with above-room-temperature dielectric phase transition

“…As a result, some dielectric phase transition hybrid have been developed using 3-, 5-, 6-and 7-heterocyclic organic amines. [15][16][17][18][19][20][21][22] For example, bis(cyclohexylaminium) tetrabromo lead, a layered hybrid compound, which has excellent dielectric switching performance, that is, the dielectric constant values vary from 25 to 400 at different temperature, which features an excellent property of dielectric switching. 23 Recently reported (hexamethyleneimine)PbBr 3 , a one-dimensional ABX 3 -type perovskite-like hybrid, also exhibits a phase transition with high dielectric switching property.…”
