2-(4-Chloro­phen­yl)chromen-4-one

Abstract

The title compound, C15H9ClO2, 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° with respect to the chromen-4-one skeleton. In the crystal, pairs of mol­ecules are inter­connected by weak Cl⋯Cl inter­actions [3.3089 (10) Å] forming dimmers which are further peripherally connected through inter­molecular C—H⋯O hydrogen bonds
