Benzophenone analogue (3) has been synthesized and characterized by X-ray diffraction method. The compound crystallizes in monoclinic space group P21/a with cell parameters a = 10.9500(7)Å, b = 10.9670(7)Å, c = 11.0740(7)Å and Z = 4. The structure exhibits intermolecular hydrogen bonding of the type C-H···O. The dimer structure is observed in the molecular packing diagram. The methoxy and chloro substituents play an important role for their biological activity.
