چکیده
The title compound, C(25)H(26)O(2), crystallizes with two crystallographically independent mol-ecules in the asymmetric unit. The differences between the two mol-ecules are marginal. The three benzene rings of each mol-ecule are in a propeller orientation and the 1,3-dioxane ring adopts a chair conformation.
