摘要：
C17H14O4, M(r) = 282.3, triclinic, P-1, a = 8.469(3), b = 8.516(2), c = 20.425(8)angstrom, alpha = 84.95(3), beta = 81.98(3), gamma = 70.47(2)degrees, V = 1373(13)angstrom3, Z = 4, D(x) = 1.365 g cm-3, lambda(MoKalpha) = 0.71069 angstrom, mu = 0.91 cm-1, F(000) = 592, T = 294K, R = 0.038 for 3577 observed reflections (F > 3sigma (F)). The asymmetric unit is composed of two molecules. These two molecules, which are in planar conformations, differ in 4'-methoxyl group orientation. Short intramolecular contacts are found between the gamma-benzopyran portion and the dimethoxyphenyl ring.
