In the title compound, C(23)H(24)N(2)O(7), the central 4H-pyran ring adopts a flattened boat conformation, whereas both cyclo-hexenone rings adopt envelope conformations, the C atom bearing the dimethyl substituent being the flap atom in each case. The mean and maximum deviation of the pyran ring are 0.0379 (4) and 0.0605 (3) Å. The mean plane of the pyran ring and the dinitro-benzene ring make a dihedral angle of 85.88 (2)°.
在标题化合物C₂₃H₂₄N₂O₇中，中心的4H-吡喃环呈扁平船式构象，而两个环己烯酮环均呈信封式构象，在每种情况下，带有二甲基取代基的C原子为折叶原子。吡喃环的平均偏差和最大偏差分别为0.0379 (4) Å和0.0605 (3) Å。吡喃环的平均平面与二硝基苯环的二面角为85.88 (2)°。
