The crystal structure N-methyl-9-(4-bromophenyl)-1,8-dioxo-1,2,3,4,5,6,7,8,9,10- decahydroacridine(C20H20BrNO2) was determined by single-crystal X-ray diffraction analysis. It belongs to P21/n space group, with a = 10.7999(18), b = 13.845(3), c = 11.4031(3) (A), β = 99.324(4)°, Dc = 1.525 g/cm3, Z = 4, λ = 0.71070(A), μ(MoKα = 2.455 mm-1, Mr = 386.28, V = 1682.5(5) (A)3, F(000) = 792, the final R = 0.0463 and wR = 0.1053. In the crystal structure, the pyridine ring adopts a boat conformation, the two six-numbered rings fused with pyridine ring adopt twisting boat con- formation.
