2,9,12,15,18,25,27,34,37,40,43,50-Dodeca­oxa-56-aza­hepta­cyclo­[24.24.5.1^51,55.0^3,8.0^19,24.0^28,33.0^44,49]hexa­penta­conta-3,5,7,19(24),20,22,28(33),29,31,44,46,48,51,53,55-penta­deca­ene

The title compound, C₄₃H₄₅NO₁₂, was prepared from the reaction of 2,6-bis­(dibromo­meth­yl)pyridine and bis­phenol 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, mol­ecules are linked by weak C—H...O and C—H...π inter­actions, forming a folded structure.
