A new organometallic compound challenges a fundamental principle of textbook chemistry

For much than a century, the well-known 18-electron regularisation has guided the tract of organometallic chemistry. Now, researchers astatine Okinawa Institute of Science and Technology (OIST), successful collaboration with scientists from Germany, Russia, and Japan, person successfully synthesized a caller organometallic compound that challenges this longstanding principle. They person created a unchangeable 20-electron derivative of ferrocene, an iron-based metal-organic complex, which could pb to breathtaking possibilities successful chemic science.
