چکیده
The title compound, C(43)H(45)NO(12), was prepared from the reaction of 2,6-bis-(dibromo-meth-yl)pyridine and bis-phenol in the presence of caesium carbonate as a base. The central ring makes dihedral angles of 64.83 (6), 13.48 (6), 56.96 (6) and 66.21 (6)° with the peripheral rings. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯π inter-actions, forming a folded structure.

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-ecul...
