چکیده
In the title compound, C(16)H(18)N(2)O(6), the dihedral angle between the aromatic ring planes is 8.11 (6)°. One of the O atoms is disordered over two sites of equal occupancy. In the crystal structure, aromatic π-π stacking [centroid-to-centroid separation = 3.5503 (8) Å] helps to consolidate the packing.
