3-Methyl-4-oxo-2-phenyl-4H-chromene-8-carboxylic acid

In the title compound, C(17)H(12)O(4), the chromene unit is approximately planar, the maximum deviation from the mean plane being 0.0166 Å. The attached phenyl ring makes a dihedral angle of 53.2 (1)° with the fused ring system. The packing of the mol­ecules in the crystal structure is governed by C...

description In the title compound, C(17)H(12)O(4), the chromene unit is approximately planar, the maximum deviation from the mean plane being 0.0166 Å. The attached phenyl ring makes a dihedral angle of 53.2 (1)° with the fused ring system. The packing of the mol­ecules in the crystal structure is governed by C—H⋯O and O—H⋯O hydrogen-bonding inter­actions.
