چکیده
The title compound, C(25)H(18)N(2)O(6), is a naphthalenophane styled in the manner of Warrener's alicyclic cyclo-phanes or mol-ecular racks wherein a trimethyl-ene tether is perfectly staggered between the two N atoms such that the central methyl-ene H atoms point toward the naphthalene π-system. The dihedral angle between the mean planes of the two benzene rings is 7.61 (7)°.
