Observation of inter- and intramolecular CH⋯F hydrogen bonding in Gingrasʹ salt: [n-Bu4N]+[Ph3SnF2]−

The crystal and molecular structure of Gingrasʹ salt [n-Bu4N]+ [Ph3SnF2]− is reported, which reveals a variety of inter- and intramolecular CH⋯F hydrogen bonding interactions. A 119Sn MAS-NMR spectrum was recorded and a tensor analysis has been performed according to the method of Herzfeld and Berger. The results are discussed in terms of the molecular structure and are compared with the parent compound Ph3SnF as well as with Mes3SnF (Mes=mesityl).
