Abstract

The molecule of the title compound, C19H20O 2S, corresponds to a chiral sulfinyldienol with two stereogenic centres, viz. the C atom susbtituted by the hydroxy group and the sulflnyl S atom. The molecule displays a V-shape in the solid state. The dihedral angle defined by the least-squares planes of the aromatic rings is 72.9 (1)°. The packing pattern exhibits the following intermolecular hydrogen bonds: one O-H⋯O [H⋯O = 1.98 Å, O⋯O = 2.785 (4) Å and O-H⋯O = 166°] and two C-H⋯O [H⋯O = 2.58 and 2.60 Å, C⋯O = 3.527(5) and 3.347 (5) Å, and C-H⋯O = 164 and 134°]. These define a chain along b. © 2006 International Union of Crystallography.
