4-[Bis(4-fluorophenyl)methyl]piperazin-1-ium 2-(2-phenylethyl)benzoate

The asymmetric unit of the title salt, C17H19F2N2+.C15H13O2−, derived from a 1,4-diazacyclohexane derivative and a carboxylic 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
