In the title compound (systematic name: 3,7,9-trihydr­oxy-1-methyl-6H-benzo[c]chromen-6-one), C(14)H(10)O(5), the methyl group is shifted out of the molecular plane due to a steric collision, thus causing a slight twist of the benzene rings. The mol­ecular structure is stabilized by an intra­molecul...

Descripción
Sumario:In the title compound (systematic name: 3,7,9-trihydr­oxy-1-methyl-6H-benzo[c]chromen-6-one), C(14)H(10)O(5), the methyl group is shifted out of the molecular plane due to a steric collision, thus causing a slight twist of the benzene rings. The mol­ecular structure is stabilized by an intra­molecular O—H⋯O hydrogen bond, generating an S(6) ring. In the crystal, mol­ecules are connected by inter­molecular O—H⋯O hydrogen bonds into a three-dimensional network.
