In the title compound, C 46 H 50 O 12 ·2CH 2 Cl 2 , each dual 20-crown-6 unit crystallizes with two di­chloro­methane solvent mol­ecules. The crown unit mol­ecule lies about an inversion centre located at the central benzene ring. The two crown ring groups adopt an  anti  conformation, stabilized by weak intra­molecular C—H⋯O inter­actions. In the crystal, the crown unit mol­ecules and the solvent mol­ecules are linked by C—H⋯O inter­actions into a three-dimensional network.
