摘　　要：The title compound （C16H14BrNO） has been synthesized by the reaction of p-tolylamine, Meldrum’s acid and 4-bromo-benzaldehyde, and its structure was characterized by IR, 1H NMR and X-ray single-crystal diffraction. The crystal belongs to monoclinic, space group P21/n with a = 7.6850（11）, b = 8.3004（11）, c = 21.301（3）A, β = 95.110（2）°, V = 1353.4（3） A^3, Mr = 316.19, Z = 4, Dc = 1.552 g/cm^3, μ（MoKα） = 3.028 mm-1, F（000） = 640, the final R = 0.0345 and wR = 0.0768. X-ray analysis reveals that the atoms of C（1）, C（2）, C（3）, C（4）, C（5） and N（1） form a six-membered ring of boat conformation.The title compound （C16H14BrNO） has been synthesized by the reaction of p-tolylamine, Meldrum’s acid and 4-bromo-benzaldehyde, and its structure was characterized by IR, 1H NMR and X-ray single-crystal diffraction.
