Key Points

The central aim is to develop and analyze a new open framework that effectively adsorbs Sr2+ ions.
Developed a supertetrahedral cluster-based open framework for ion exchange.
Examined the framework's capabilities for Sr2+ adsorption against competing ions.
Analyzed the synergistic effects of size-matching and soft-base interactions.
The framework exhibited significantly higher Sr2+ adsorption compared to other competing ions.
Demonstrated effective ion exchange properties with a high capacity for Sr2+ uptake.

Abstract
