文摘

The magic number boron cluster B₁₃⁺ previously termed as a “molecular Wankel motor”, is predicted to exhibit an exceptional fluxionality already at low temperatures. In their Communication on i.org/10.1002/anie.201609766" rel="references:https://doi.org/10.1002/anie.201609766">page 505 ff., K. R. Asmis et al. spectroscopically confirm the structural assignment to a planar boron double wheel species and present the first experimental evidence for the quasi-rotation of the inner B₃-ring using cryogenic ion vibrational spectroscopy of B₁₃⁺ combined with density functional theory computations and Born–Oppenheimer molecular dynamics simulations.
