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.

For more than a century, the well-known 18-electron rule has guided the field of organometallic chemistry. Now, researchers at Okinawa Institute of Science and Technology (OIST), in collaboration with ...

Organometallic chemistry centres on the study of compounds that incorporate at least one direct bond between a metal centre and a carbon atom. Over the past century, this field has evolved from the ...

Sandwich compounds are special chemical compounds used as basic building blocks in organometallic chemistry. So far, their structure has always been linear. Recently, researchers made stacked sandwich ...
