| dc.description.abstract | The title compound, C20H16O5, [systematic name: 5-hydroxy-7-(4-hydroxyphenyl)-2,2-dymethuyly-2H, 6H=benzol (1, 2-b:5, 4-b)] – dipyran-6-one], was obtained by demethylation of the biologically active related compound, 4-O methylaphinumiso-flavone. The molecular structure of the title compound is characterized by a fused tricyclic system that contains an approximately planar benzopyrone ring fragment. The six membered pyran ring adopts a half-chair conformation. Both ring systems show an out-of-plane twist. The dihedral angle between the mean plane of the benzopyrone system and the benzene ring is 54.29(3)o. The molecules are linked by O-H … hydrogen bonds, forming a molecular tape running along the b axis. | en_US |
