title: 4-[Bis(4-fluorophenyl)methyl]piperazin-1-ium 2-(2-phenylethyl)benzoate.
abstract: The asymmetric unit of the title salt, C(17)H(19)F(2)N(2) (+.)C(15)H(13)O(2) (-), derived from a 1,4-diaza-cyclo-hexane derivative and a carb-oxy-lic acid, contains two formula units. The cation is protonated at the secondary amine functionality. The six-membered heterocycles adopt chair conformations. The fluorophenyl rings in the two cations make dihedral angles of 77.21 (19) and 78.8 (2)° while the aromatic rings in the anions enclose angles of 69.5 (2) and 69.9 (2)°. In the crystal, classical N-H⋯O hydrogen bonds as well as C-H⋯F and C-H⋯O contacts connect the entities into layers parallel to ac.
