3,4-(4-Methoxybenzo):8,9-benzobicyclo[4.4.1]undeca-3,8-dien-11-one ethylene acetal.
The title compound, 5-methoxyspiro[tetracyclo[8.8.1.0(3,8).0(12,17)]nonadeca-3,5,7,12,14,16-hexene-19,2'-[1,3]dioxolane], C(22)H(24)O(3), exhibits a twin-chair conformation with the aromatic rings overlying each other. Comparison of the dihedral angle between these two rings with those from previously reported [3.3]orthocyclophanes of this type suggests the presence of a weak attractive charge-transfer interaction between the two, different, stacked arenes.
