title: (E)-3-(4-Chloro-phen-yl)-1-(5-hy-droxy-2,2-dimethyl-2H-chromen-6-yl)prop-2-en-1-one.
abstract: There are two independent mol-ecules in the asymmetric unit of the title compound, C(20)H(17)ClO(3), each having an E configuration about the -C=C- bond. The dihedral angles between the two benzene rings in the two mol-ecules are 7.17 (11) and 9.82 (11)°. In both mol-ecules, the hy-droxy group is involved in an intra-molecular O-H⋯O hydrogen bond.
