title: 8-Hydr-oxy-5,6,7-trimeth-oxy-2-phenyl-4H-chromen-4-one.
abstract: In the title compound, C(18)H(16)O(6), the benzopyran group is essentially planar, with the O atoms of the substituent groups lying close to its mean plane. The mol-ecular conformation is governed by intra-molecular inter-actions. The crystal packing is mainly determined by one classical inter-molecular hydrogen bond which gives rise to the formation of an infinite chain along the a axis.
