摘要：
7-(Diethylamino)-3-(4-aminophenyl)coumarin has been synthesized in a new one-pot synthesis by a three-step process starting from 4-(diethylamino)salicylaldehyde and 4-nitrophenylacetonitrile. The product was obtained in a good yield with a high degree of purity and characterized by NMR, IR and HR-MS. The orange crystals of the title compound were grown from ethyl acetate solution. The solid state structure was established by X-ray crystallography analysis. The crystal belongs to the orthorombic system, space group Pccn with a= 11.1095(5), b = 33.0187(15), c = 17.2865(7) angstrom, V = 6341.1(5) angstrom(3), C19H2ON2O2, M-r = 308.37, P-calc = 1.292 g.cm(-3), mu = 0.085 mm-1, F(000) = 2624, the fmal R= 0.0480 and wR = 0.1265 (I> 2 sigma(I)).
