The title compound, C(15)H(9)ClO(2), is a synthetic flavonoid obtained by the cyclization of 3-(4-chlorophenyl)-1-(2-hydroxyphenyl)prop-2-en-1-one. The 4-chlorophenyl ring is twisted at an angle of 11.54 degrees with respect to the chromen-4-one skeleton. In the crystal, pairs of molecules are interconnected by weak Cl center dot center dot center dot Cl interactions [3.3089 (10) angstrom] forming dimmers which are further peripherally connected through intermolecular C-H center dot center dot center dot O hydrogen bonds.
