Background:

Perovskite materials (ABX3) are known for diverse properties and chemical versatility.
Existing perovskites primarily use ionic components at A-, B-, and X-sites.
A need exists for expanding the chemical space of perovskites to unlock new functionalities.

Purpose of the Study:

Introduce a novel subclass of three-dimensional ABX3 perovskites.
Utilize neutral molecules as the X-site component.
Investigate the structural and ferroelastic properties of these new materials.

Main Methods:

Synthesis of novel ABX3 perovskites with neutral 1,4-dioxane as the X-site.
Structural characterization of (PF6)Na(1,4-dioxane)3 and (ClO4)Ag(1,4-dioxane)3.

Keywords:

Investigation of ferroelastic transitions using temperature-dependent studies.

Main Results:

Demonstrated stable 3D perovskite frameworks with neutral X-sites within Goldschmidt tolerance.
(PF6)Na(1,4-dioxane)3 exhibits a ferroelastic transition at 290 K.
(ClO4)Ag(1,4-dioxane)3 shows successive ferroelastic transitions and switchable birefringence.

Conclusions:

The introduction of neutral X-site molecules significantly expands chemical flexibility in ABX3 perovskites.
This new subclass enables precise modulation of structural and functional properties.
These findings open avenues for novel material functionalities and applications.
