The title compound, C30H18Cl6O3·0.82CH2Cl2, consists of a slightly cup-shaped seven-ring truxene nucleus with hydroxy and dichloromethyl substituents at stereocenters 5R/S, 10R/S and 15R/S. C—Cl distances are in the range 1.759 (4)–1.783 (3) Å. Solvent channels parallel to the b axis appear to be partially occupied by highly disordered dichloromethane solvent molecules, the contribution of which were removed from the refinement with the SQUEEZE procedure in PLATON [Spek (2009). Acta Cryst. D65, 148–155]. Only one of the OH groups forms a hydrogen bond, which is intermolecular to another OH group, forming centrosymmetric dimers in the crystal.
