摘要：

The structure of the new flavone reported here has a general shape defined by a phenyl ring rotated by 62.2(1)degrees from the plane of the gamma-benzopyranone portion. The two methoxy groups have the expected conformations: out of plane for the methoxy group at C2' and in plane for the other at C3'. The major influence on the packing appears to be the O6-H6...O4 intermolecular hydrogen bond.
