Abstract: In the title compound, C₃₄H₂₈O₆·0.5C₇H₈, the calix[4]arene molecule forms a cone-like conformation, stabilized by intramolecular O-HO hydrogen bonds. In the crystal structure, the calixarene molecules form centrosymmetric dimers via aromatic - interactions [centroid separation = 3.633 (3) Å]. The toluene solvent molecule is disordered about an inversion centre.
