Organometallic compounds, which are molecules consisting of metal atoms and organic molecules, are commonly used to accelerate chemical reactions. One specific type of these compounds, known as metallocene, is highly regarded for its versatility and unique “sandwich structure.”
A crucial breakthrough has been achieved by Dr. Satoshi Takoebayashi from the Okinawa Institute of Science and Technology (OIST) in collaboration with scientists from Germany, Russia, and Japan. They have successfully developed a new 21-electron metal-facial compound at OIST. Typically, the structure of metallocene can contain up to 20 electrons, but the 18-electron compound is considered the most stable.
Dr. Takoebayashi explained, “Adding two electrons to a 19-electron metal-carrier created a 21-electron compound, which was previously thought to be unlikely. However, this 21-electron compound can be stably obtained in solutions and solid substances and can be stored for extended periods of time.”
This innovative compound has the potential to serve as a foundation for the development of new materials in fields such as medicine, catalysis, and energy. The most challenging aspect of the study involved providing evidence that nitrogen successfully bonded with cobalt without altering the sandwich structure. To achieve this, Dr. Takebayashi assembled a team of specialists who meticulously demonstrated the correct bonding of all the elements involved.
“This breakthrough would not have been possible without the tremendous efforts of my colleagues,” added Dr. Takebayashi.
The details of this groundbreaking discovery have been published in the scientific journal Nature Communications. In future investigations, the researchers intend to explore the application of 21-electron metal facial compounds in areas such as catalysis and materials science.
