摘　　要：The title compound （C28H19Cl2N） has been synthesized by the reaction of dibenzoylmethane and N-（4-chlorobenzylidene）-4-chlorobenzenamine promoted by low-valent titanium reagent, and characterized by elemental analysis, IR, ^1H NMR and X-ray single-crystal diffraction. The crystal belongs to monoclinic, space group P2 1/C with a = 9.952（2）, b = 9.863（2）, c = 23.460（6） A, β = 99.62（2）°, V = 2270.4（9） A^3, Mr = 440.34, Z = 4, Dc = 1.288 g/cm^3, μ（MoKa） = 0.301 mm^-1, F（000） = 912, the final R = 0.0387 and wR = 0.0793. X-ray analysis reveals that the four phenyl rings in the pyrrole ring are not coplanar.The title compound （C28H19Cl2N） has been synthesized by the reaction of dibenzoylmethane and N-（4-chlorobenzylidene）-4-chlorobenzenamine promoted by low-valent titanium reagent, and characterized by elemental analysis, IR, ^1H NMR and X-ray single-crystal diffraction.
