In the cation of the title salt {systematic name: 4-[bis(4-fluorophenyl)methyl]-1-[(2E)-3-phenylprop-2-en-1-yl]piperazin-1-ium hydrogen maleate}, C26H27F2N2+·C4H3O4−, the protonated piperazine ring is in a chair conformation. The dihedral angle between the 4-fluorophenyl rings is 68.2 (2)°. An intramolecular O—H...O hydrogen bond occurs in the anion. In the crystal, N—H...O, C—H...O and C—H...F interactions are observed, which link the ions into [001] chains.
