Crystal structures of the hexafluoridophosphate salts of the isomeric 2-, 3- and 4-cyano-1-methylpyridinium cations and determination of solid-state interaction energies

The synthesis and crystal structures of the isomeric molecular salts 2-, 3- and 4-cyano-1-methylpyridinium hexafluoridophosphate, C7H7N2+·PF6−, are reported. In 2-cyano-1-methylpyridinium hexafluoridophosphate, C—H...F hydrogen bonds form chains extending along the c-axis direction, which are associ...
