A compound of 4-(2-methylene-1-ethyl-3,3-dimethylindoline-2 -yl)-6-nitryl-1 -ethyl-3 ,3 -di- methylspiro[3,4-dihydro-2H-1-benzopyran-2,2 -indoline] has been synthesized by the reaction of excess indoline with 5-nitrosalicylaldehyde in refluxing ethanol. The molecular structure was characterized by 1H NMR, IR spectra and elemental analysis. Meanwhile, the crystal of the compound was obtained and determined by X-ray diffraction study. Crystal data for this compound: monoclinic, space group P2/n, a＝1.2476(3) nm, b＝1.1939(2) nm, c＝2.0317(4) nm, α＝90°, β＝107.45(3)°, γ＝90°, D＝1.205 g/cm, μ＝0.077 mm, F(000)＝1120, V＝2.8871(10) nm, Z＝4.

Key words: dicondensed spiropyran, characterization, crystal sructure
