A Crystalline Stannyne.
Nat. Chem. 2024;

Key words
stannyne - bulky cyclic phosphino ligand - heavy atom - group 14 element
Significance
Alkyne analogues containing heavier group 14 elements are typically unstable and not isolable. In this work, a crystalline base-free stannnye that is persistent at room temperature is synthesized and isolated.
Comment
By virtue of a bulky cyclic phosphino ligand, the stannyne is stabilized and isolable at room temperature in nitrogen atmosphere, with a single-crystal structure unveiled. Having four resonance forms, the stannyne shows the reactivity of both a carbene and stannylene.
