5-Hydroxy-7-phenyl-5-(prop-2-yn-1-yl)-5,6-dihydro-1-benzofuran-2(4H)-one monohydrate

Abstract

In the title compound, C17H14O3·H2O, 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 mol­ecule, and the hy­droxy and carbonyl groups of the organic compound. These inter­actions form a square-like supra­molecular synthon unit which propagates as chains parallel to the crystallographic b axis. A C—H⋯O interaction also occurs.
