Scientists at OIST have defied a foundational rule in chemistry by creating a stable 20-electron version of ferrocene—an organometallic molecule once thought to be limited to 18 valence electrons.

Organometallic complexes have emerged as pivotal systems for probing electron transfer mechanisms, owing to their ability to couple metal centres with organic ligands to create versatile molecular ...

With six Nobel Prizes in the category, organometallic chemistry has been a widely explored field since the 1950s. Yet, the discovery of new classes of organometallic compounds remains a rare ...
