Abstract

The asymmetric unit of the title compound, C(29)H(29)ClO(11), contains two independent mol-ecules of similar geometry, both adopting an E conformation about the C=C double bond. The dihedral angles formed by benzene rings are 10.73 (16) and 13.79 (18)°. The pyran-oside rings adopt a chair conformation. Intra-molecular C-H⋯O close contacts occur. The crystal packing is stabilized by inter-molecular C-H⋯O hydrogen bonds.
