摘要：

C17H14O5, M(r) = 298.29, monoclinic, I2/a, a = 15.538 (6), b = 11.919 (4), c = 16.083 (4) angstrom, beta = 104.72 (12)-degrees, V = 2881 (2) angstrom 3, Z = 8, D(x) = 1.375 g cm-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 0.95 cm-1, F(000) = 1248, T = 294 K, R = 0.051 for 1898 observed reflections [F > 1-sigma(F)]. The general shape of the molecule can be defined by two different regions: the chromone atoms including the O atom of the hydroxyl group lie in a plane, while the phenyl atoms including the O atoms of the methoxy groups lie in another plane. The angle between these mean planes is 68.2-degrees.
