<p dir="ltr">Since their discovery in 1973, transition metal Fischer carbynes have become a foundational class of metal-carbon triple bond in organometallic chemistry.
Description
However, even though the uranium Fischer carbyne bonding motif has been a fundamental target in f-element chemistry, its isolation has remained challenging. Here, we report the synthesis and characterization of the uranium Fischer-type carbyne complex [N"<sub>3</sub>U(m-CNN)UN"<sub>3</sub>] (N" = N(SiMe<sub>3</sub>)<sub>2</sub>).
Single-crystal X-ray diffraction analysis reveals a uranium-carbyne distance of 2.379(15) Å, and density functional theory calculations combined with experimental Quantum Crystallography Hirshfeld Atom Refinement reveal the presence of two-electron C-->U s donation, weak two-electron C-->U p-donations, and two orthogonal one-electron U-->C p-back-bonds, demonstrating s<sup>2</sup>p<sup>1</sup>p<sup>1</sup> Fischer-type carbyne bonding overall.

This work redefines the range of bonding modes for the diazomethanediide ligand and provides a uranium-carbon triple bond interaction that is related, yet distinct, to transition metal Fischer carbynes, providing a basis to develop and understand f-element carbyne chemistry.</p>
