2-(4-Hy-droxy-phen-yl)-3-meth-oxy-4H-chromen-4-one.

ABSTRACT: In the title compound, C16H12O4, the substituent benzene ring and meth-oxy group are twisted relative to the 4H-chromene skeleton by 24.1?(1) and 61.3?(1)°, respectively. In the crystal, mol-ecules are connected by classical O-H?O and weak C-H?O hydrogen bonds, forming chains parallel to [201]. The 4H-chromene ring systems of adjacent mol-ecules are either parallel or inclined at an angle of 28.9?(1)°.

In the title compound, C16H12O4, the substituent benzene ring and meth-oxy group are twisted relative to the 4H-chromene skeleton by 24.1 (1) and 61.3 (1)°, respectively. In the crystal, mol-ecules are connected by classical O-H⋯O and weak C-H⋯O hydrogen bonds, forming chains parallel to [201]. The 4H-chromene ring systems of adjacent mol-ecules are either parallel or inclined at an angle of 28.9 (1)°. ...[more]
