Abstract | Full Text

The title compound, C40H40O9, is a product of the double crotonic condensation of bis(2-acetylphenoxy)-3-oxapentane with bis(2-formylphenoxy)-3,6-dioxaoctane. The title macromolecule includes the 31-crown-7-ether skeletal unit and adopts a saddle-like conformation. The two ethylene fragments have E configurations. The volume of the internal cavity of the macrocycle is approximately 125 Å3. In the crystal, the molecules are arranged at van der Waals distances.
