4-[Bis(4-fluorophenyl)methyl]piperazin-1-ium 2-hydroxybenzoate 2-hydroxybenzoic acid monosolvate

Abstract

The title compound, C17H19F2N2+·C7H5O3−·C7H6O3, is a co-crystal from 4-[bis(4-fluorophenyl)methyl]piperazin-1-ium, salicylate anion and salicylic acid in a 1:1:1 ratio. In addition to an intramolecular O—H...O hydrogen bond, the crystal packing shows hydrogen bonds between the piperazinium cation and salicylate anion (N—H...O), as well as between the salicylic acid molecule and anion (O—H...O), giving rise to a three-dimensional network.
