In the solvated salt derived from 2,4-dichlorophenol, tert
-butylamine, 2,6-dichlorophenol and tetrahydrofuran, five components, namely two tert
-butylammonium cations, one 2,4-dichlorophenol molecule, one 2,4-dichlorophenolate anion and one 2,6-dichlorophenolate anion, are bound by N—H⋯O and O—H⋯O hydrogen bonds to form a hydrogen-bonded ring with the graph-set motif
(10), which is further associated with two pendant tetrahydrofuran solvent molecules by N—H⋯O hydrogen bonds. The hydrogen-bonded ring has internal symmetry, with a twofold axis running through the centre of the 2,6-dichlorophenolate anion, and is isostructural with a previous structure.
