4-Hy­droxy-3-[(E)-3-phenyl­prop-2-eno­yl]-2H-chromen-2-one

In the title mol­ecule, C(18)H(12)O(4), the phenyl ring is twisted by 23.2 (1)° from the mean plane of the chromene system. In the crystal, weak inter­molecular C—H⋯O hydrogen bonds link mol­ecules into zigzag chains extending in the [010] direction. An intra­molecular O—H⋯O hydrogen bond is also pr...

Sumario:In the title mol­ecule, C(18)H(12)O(4), the phenyl ring is twisted by 23.2 (1)° from the mean plane of the chromene system. In the crystal, weak inter­molecular C—H⋯O hydrogen bonds link mol­ecules into zigzag chains extending in the [010] direction. An intra­molecular O—H⋯O hydrogen bond is also present.
