In the title compound, C6H5Cl3N+·ClO4−·C12H24O6, the perchlorate anion is disordered over two orientations in a 0.666 (17):0.334 (17) ratio. The ammonium group of the organic cation inserts into the crown ether ring and forms three bifurcated N—H⋯(O,O) hydrogen bonds to generate a supra­molecular complex. The macrocycle has approximate D3d local symmetry.
