abstract: In the title compound, C46H50O12·2CH2Cl2, each dual 20-crown-6 unit crystallizes with two di-chloro-methane solvent mol-ecules. The crown unit mol-ecule lies about an inversion centre located at the central benzene ring. The two crown ring groups adopt an anti conformation, stabilized by weak intra-molecular C-H⋯O inter-actions. In the crystal, the crown unit mol-ecules and the solvent mol-ecules are linked by C-H⋯O inter-actions into a three-dimensional network.
