Abstract: (2E)-1-(Anthracen-9-yl)-3-(3,4-dichlorophenyl)prop-2-en-1-one. C23H14OCl2, crystallizes in the monoclinic space group P 21/c with unit cell parameters, a= 13.7669(9)Å, b= 11.8400(10)Å, c= 11.3285(8) Å, β = 103.525(6)° and number of molecules per unit cell (Z)= 4. The crystal structure was solved by direct methods and refined by full matrix least square procedure to a final R-value of 0.067 for 2233 observed reflections. The dihedral angle between the benzene and anthracene moiety of the molecule is 89.43(1)°.The structure is stabilized by two C–H⋅⋅⋅O intermolecular interaction. Aromatic π-π stacking interaction has also been observed in the structure.
