A groundbreaking Chinese research team has successfully synthesized the first-ever rare earth triple bond compound, dispelling the long-held notion that rare earth elements are incapable of forming triple bonds. Leveraging fullerene molecular cages, the team stabilized the cerium-carbon triple bond and validated its existence through rigorous experimental procedures and theoretical calculations. This remarkable achievement underscores the versatility of bonding mechanisms in rare earth elements, paving the way for innovative advancements in the theory of rare earth chemical bonds and the design of cutting-edge materials.
