Conclusions. In summary, we report gis-ZIF-1 as a solid-state nanomachine, wherein CBUs function as intricate mechanical components, facilitating ZIF mechanics analogous to a slidercrank mechanism. The unique mechanics of gis-ZIF-1 originated from molecular movements, resulting in flexible OTO angles, markedly different from other frameworks, such as zeolites and Cu-based ZIFs (see Table ). By employing mathematical formulations, we have precisely modeled the mechanics of gis-ZIF-1, resembling its macroscopic counterparts.
