The title compound (C13H10N2OCl2, Mr = 281.13) was synthesized and its crystal structure was determined by X-ray analysis. The crystal belongs to orthorhombic system, space group P22121 with a = 4.589(1), b = 9.725(1), c = 14.385(1) Å, V = 642.0(7) Å3, Z = 2, Dc = 1.454Mg·m-3, F(000) = 288, μ (MoKα) = 0.493mm-1, final R = 0.0466, ωR = 0.1216 for 662 observable reflections with I>2σ(I). In the crystal of the title compound, the molecule has a crystallographic two-fold axis through C(1)-O(1) bond of the carbonyl group. The molecules in the crystal are linked together by a bifurcated N - H⋯O intermolecular hydrogen bond to form a ribbon extending along the a axis and the aromatic stock effect exists.
