Abstract
3,5,7-Trihydroxy-8-methoxy-2-(4-methoxy-phenyl)-4H-1-benzopyran-4-one, C17H14O7, M(r) = 330.3, triclinic, P1BAR, a = 6.579 (5), b = 8.441 (7), c = 13.893 (14) angstrom, alpha = 101.92 (9), beta = 103.38 (6), gamma = 97.44 (6)-degrees, V = 721 angstrom 3, Z = 2, D(x) = 1.52 g cm-3, Mo K-alpha radiation, lambda = 0.71069 angstrom, mu = 1.2 cm-1, F(000) = 344, T = 200 K, R = 0.076 for 1534 unique observed [I/sigma(I) greater-than-or-equal-to 2.0] reflections. The definitive structure of prudomestin is established by this investigation. The molecule is essentially planar with the methyl groups projecting above and below the plane. The major intermolecular force within a layer of molecules in the solid state results from hydrogen bonding.
