Abstract: The title complex, 2C12H24N+·C6H3Cl2O-·C6H2Cl3O-·C6H4Cl2O, consists of three different achiral components, dicyclohexylammonium cations, 2,4,6-trichlorophenolate anions and H-atom-bridged 2,4-dichlorophenolate/2,4-dichlorophenol units, held together by O-HN and O-HO hydrogen bonds to form a chiral hydrogen-bonded ring. A helical cylinder is established by the packing of these rings along a crystallographic 41 screw axes. Helical cylinders may be generated from each other by translation, resulting in the formation of the chiral crystal. Neighbouring parallel helical cylinders are associated by van der Waals interactions only.
