Three 4-(4-fluorophenyl)piperazin-1-ium salts containing organic anions: supramolecular assembly in one, two and three dimensions

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2020
Three salts containing the 4-(4-fluorophenyl)piperazin-1-ium cation have been prepared and structurally characterized. In 4-(4-fluorophenyl)piperazin-1-ium 2-hydroxy-3,5-dinitrobenzoate, C10H14FN2+·C7H3N2O7−, (I), the anion contains an intramolecular O—H.
