Hepburnin
Hepburnin is a fictional chemical compound created for use in science fiction and thought experiments about catalysis and energy storage. It does not refer to a substance verified in the chemical literature. In typical fictional or speculative descriptions, Hepburnin is an organometallic complex featuring a central transition metal bound to a highly conjugated, nitrogen-rich ligand framework, producing redox-active behavior and potential multi-electron transfer capabilities. The term is often employed to illustrate how ligand electronics influence catalytic turnover, selectivity, and stability across different oxidation states.
