The title compound ethyl(2-amino-4-(3-nitrophenyl)-1,4-dihydro-2H-pyrano[3,2-h]quinolin-3-)carboxylate (C21H17N3O5, Mr= 391.38) was synthesized and crystallized. The crystal belongs to triclinic, space group P-1 with a = 7.886(1 ), b = 9.896(2), c = 12.575(3) A, α = 77.81 (2), β= 82.69(2), γ= 73.86(2)°, Z = 2, V= 919.0(3) A3, Dc = 1.414 g/cm3,μ(MoKα) = 0.103 mm -1, F(000)= 408, R = 0.0421 and wR = 0.0973 for 2007 observed reflections (I > 2σ(I)). X-ray analysis reveals that the C(6), C(7), C(10), C(11), C(12) and O(1) atoms form a six-membered ring which adopts a boat conformation. In the ring, the bond lengths of C(6)-C(7) and C(10)-C(11) are 1.360(2) and 1.361 (2) A, respectively, indicating they are C=C double bonds.
