The Lectka lab publishes in Nature Communications on the structural proof of an organic fluoronium cation.

This manuscript reports the first X-ray crystal structure of an organic fluoronium cation, thus providing an ultimate proof of its debated existence.  In addition to the crystal structure as the [SB2F11] salt, this article also discusses its vibrational spectra and detailed analysis concerning the nature of bonding situation in this fluoronium cation and its heavier halonium homologues.
