Schiff base 3-[(2-morpholinoethylimino)methyl]benzene-1,2-diol has been synthesized from the reaction of 4-(2-aminoethyl)morpholine with 2,3-dihydroxybenzaldehyde. The title compound has been characterized by elemental analysis, IR, H-1-NMR, C-13-NMR and UV-visible techniques. The structure of the compound also has been examined crystallographically. For the compound exist as dominant form of enol-imines in both the solutions and solid state. The crystal structure has been solved by direct methods and refined by full-matrix least squares. The title compound crystallize in the monoclinic space group P2(1)/n with a = 12.085(1), b = 8.256(1), c = 13.650(1) angstrom, beta = 108.56(1)degrees, V = 1291.1(2) angstrom(3), D (x) = 1.288 g cm(-3), respectively (R-1 = 0.0336 and wR(2) = 0.0922 for 2117 reflections [I > 2 sigma(1)].
