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-H···N and O-H···O 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.
标题配合物2C₁₂H₂₄N⁺·C₆H₃Cl₂O⁻·C₆H₂Cl₃O⁻·C₆H₄Cl₂O由三种不同的非手性成分组成，即二环己基铵阳离子、2,4,6-三氯苯酚阴离子以及通过氢原子桥连的2,4-二氯苯酚/2,4-二氯苯酚单元，它们通过O-H···N和O-H···O氢键结合在一起，形成一个手性氢键环。这些环沿着一个晶体学4₁螺旋轴堆积形成一个螺旋柱体。螺旋柱体可以通过平移相互生成，从而形成手性晶体。相邻的平行螺旋柱体仅通过范德华相互作用关联。
