Molecular structure of the new 20-electron ferrocene derivative, highlighting nitrogen (blue), iron (orange), hydrogen (green), and carbon (grey) atoms. For over a century, the well-known 18-electron ...

The GATE syllabus for Chemistry (CY) 2026 is divided into three sections - Physical Chemistry, Inorganic Chemistry, and Organic Chemistry. It is necessary for all the candidates who are going to ...

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 ...
