5,7-Dimeth­oxy-2-(4-methoxy­phen­yl)-4H-1-benzopyran-4-one methanol solvate monohydrate

In the title compound (alternatively called 4′,5,7-trimethoxy­flavone methanol solvate hydrate), C18H16O5·CH3OH·H2O, the flavone mol­ecule is almost planar, the inter­planar angle between the planes of the benzopyran-4-one group and the attached benzene ring being 4.69 (9)°. In the crystal, the flavone mol­ecule makes inter­molecular C—H⋯O hydrogen bonds to adjacent inversion-related flavone mol­ecules, generating R 2 2(8) and R 2 2(14) rings and an infinite ribbon. The inversion-related ribbons are stabilized through the inter­stitial water and methanol mol­ecules via inter­molecular O—H⋯O hydrogen bonds, generating R 4 2(8) and R 2 1(6) rings and C 2 2(4) chains, and are further sustained by π–π inter­actions with an inter­planar spacing of 3.365 (2)Å
