摘要：

A compound of 4-(2-methylene-1-ethyl-3,3-dimethylindoline-2'-yl)-6-nitryl-1'-ethyl-3',3'-dimethylspiro[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(1)/n, a= 1.2476(3) nm, b=1.1939(2) nm, c=2.0317(4) nm, alpha=90 degrees, beta=107.45(3)degrees, gamma=90 degrees, D-c=1.205 g/cm(3), mu=0.077 mm(-1), F(000)=1120, V=2.8871(10) nm(3), Z= 4.
