Hexamethoxyamentoflavone trihydrate

Abstract

The mol­ecular structure of the title compound [systematic name: 5,7,4′,5′′,7′′,4′′′‐hexa­meth­oxy‐3′,8′′‐biflavone trihydrate], C36H30O10·3H2O, contains two flavone groups linked by a C—C single bond. In the crystal structure, centrosymmetric clusters are formed via inter­molecular O—H⋯O hydrogen bonds involving the hexa­meth­oxy‐3′,8′′‐biflavone mol­ecules and solvent water mol­ecules.
