3-Hy­droxy-2-(4-meth­oxy­phen­yl)-4H-chromen-4-one

In the title compound, C(16)H(12)O(4), the benzene ring is twisted at an angle of 12.3 (1)° relative to the 4H-chromene skeleton, and an intramolecular O—H⋯O hydrogen bond occurs. The meth­oxy group is almost coplanar with the benzene ring [1.5 (1)°]. In the crystal, inversely oriented mol­ecules are arranged in double (A, A′) columns, along the b axis, and are linked by a network of inter­molecular O—H⋯O hydrogen bonds (between A and A′) and C—H⋯π contacts (within A or A′). The 4H-chromene cores are parallel within A or A′, but make a dihedral angle of 88.6 (1)° between A and A′.
