5,7-Dihy­droxy-3,6-dimeth­oxy-2-(4-meth­oxy­phen­yl)-4H-chromen-4-one monohydrate

The title compound, C(18)H(16)O(7)·H(2)O, is a flavonoid isolated from Dodonaea viscosa­. The benzopyran ring system of the flavonoid is essentially planar [maximum deviation = 0.025 (2) Å] and inclined at 5.83 (2)° to the attached benzene ring. The water of hydration is involved in extensive hydrog...

description The title compound, C(18)H(16)O(7)·H(2)O, is a flavonoid isolated from Dodonaea viscosa­. The benzopyran ring system of the flavonoid is essentially planar [maximum deviation = 0.025 (2) Å] and inclined at 5.83 (2)° to the attached benzene ring. The water of hydration is involved in extensive hydrogen bonding, assembling the mol­ecules into a supra­molecular network via classical inter­molecular O—H⋯O hydrogen bonding. The crystal structure is further stabilized by π–π stacking inter­actions [centroid–centroid distance between benzene rings = 3.564 (3) Å].
