L-Histidinium Tetrafluorosuccinate

Abstract

The crystal structure of the C<inf>6</inf>N<inf>11</inf>N<inf>3</inf>O <inf>2</inf>2+·C<inf>4</inf>F<inf>4</inf>O<inf>4</inf> 2- was investigated. To prepare the compound, the calculated amount of L-histidine and tetrafluorosuccinic acid was dissolved in doubly distilled water using a magnetic stirrer. Neutron and x-ray investigations on histidine hydrochloride had reported two forms of l-histidine with acetic acid, l-histidine and formic acid, and DL-histidine with glycolic acid. The crystal structure of compound was stabilized by hydrogen bonds in addition to van der Waals interactions.
