Researchers Synthesized Rare Uranium-Carbon Triple Bond
Scientists successfully isolated a uranium Fischer-type carbyne featuring a complex metal-carbon triple bond.
Updated on Oct. 5, 2026 in Chemistry
Researchers have successfully synthesized and isolated a uranium-carbon triple bond, a major milestone in f-element chemistry. The breakthrough confirms a structure involving two-way electron sharing between the atoms.
Why it matters
This achievement resolves a long-standing challenge in chemical synthesis by proving that uranium can participate in such stable bonding arrangements. It expands the known limits of how heavy elements interact with carbon at the atomic level.
The researchers identified a bond length of 2.379(15) Å between the uranium and carbon atoms. Confirmation of this structure was achieved through single-crystal X-ray diffraction, spectroscopy, magnetometry, and computational analysis.
The players
University of Manchester
This is a public research university in the United Kingdom that served as a primary institution for this chemical study.
The details
The research team created the compound by combining a uranium precursor with a carbon-atom transfer reagent. Despite the high-energy nature of such bonds, the resulting uranium Fischer-type carbyne exhibits relatively low reactivity.
