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

ABSTRACT: 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 meth-oxy group is almost coplanar with the benzene ring [1.5?(1)°]. In the crystal, inversely oriented mol-ecules are arranged in double (A, A') columns, along the b axis, and are linked by a network of inter-molecular O-H?O hydrogen bonds (between A and A') and C-H?? 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'.
