New Compounds for Organometallic Chemistry – Sandwich Complexes in the Form of Rings Are Kept Together by Their Own Energy
Sandwich compounds are special chemical compounds used as basic building blocks in organometallic chemistry. So far, their structure has always been linear. Recently, researchers of Karlsruhe Institute of Technology (KIT) and the University of Marburg were the first to make stacked sandwich complexes form a nano-sized ring. Physical and other properties of these cyclocene structures will now be further investigated.
Evolution of Sandwich Complexes
Sandwich complexes were developed about 70 years ago and have a sandwich-like structure. Two flat aromatic organic rings (the “slices of bread”) are filled with a single, central metal DOI: 10.1038/s41586-023-06192-4
