Key Points

The aim is to explore a new subclass of perovskites that maintains stability and expands chemical versatility.
Introduced a perovskite subclass with a neutral X-site.
Assessed the structural and functional properties under Goldschmidt tolerance.
The new perovskite subclass achieved stable 3D frameworks.
Significant enhancement in chemical flexibility was observed.
Potential for exotic properties and functionalities was reported.

Abstract

perovskites with a neutral X-site enables stable 3D frameworks within the Goldschmidt tolerance criteria and greatly expands chemical flexibility, allowing precise modulating of structural and functional properties. The introduction of this fundamentally new perovskite subclass opens up vast possibilities for achieving exotic properties and functionalities, further enriching this highly promising material platform.
