چکیده

In the title compound, C(17)H(14)O(3)·H(2)O, the six-membered ring, which adopts a half-chair conformation, makes a dihedral angle of 24.3 (2)° with the phenyl ring. In the crystal, the components are linked by O-H⋯O hydrogen bonds involving the water mol-ecule, and the hy-droxy and carbonyl groups of the organic compound. These inter-actions form a square-like supra-molecular synthon unit which propagates as chains parallel to the crystallographic b axis. A C-H⋯O interaction also occurs.
