The title compound (C22H18N2O3) has been synthesized by the reaction of 3,4- dimethoxybenzaldehyde, malononitrile and 1-naphthol in ethanol in the presence of piperidine, and its structure was characterized by elemental analysis, IR, 1H NMR and X-ray single-crystal diffraction. The crystal belongs to monoclinic, space group C2/c with a = 24.221(6), b = 9.016(2), c = 17.003(5) ? b = 93.16(1), V = 3707(2) ?, Mr = 358.38, Z = 8, Dc = 1.284 g/cm3, m(MoKa) = 0.087 mm-1, F(000) = 1504, the final R = 0.0432 and wR = 0.1085. X-ray analysis reveals that the atoms of C(1), C(2), C(3), C(4), C(5) and O(1) form a boat-form six-membered ring in which the C(1)C(2) (1.349(3) ? is a C=C double bond.
