Abstract
The crystal and molecular structure of ethyl a - cyano - a - (2, 4 - dinitrophenyl) phenylacetate was determined. The data of the crystal and molecular structure were collected atspacegroupP21/c,a = 0.8903(1), b = 1.2303(1), c = 1. 5119(3)nm, β = 94. 23(1)°, V =1.6515nm3, μ(MoKa)=8.951cm-1, Dc=1.429(g/cm3),Z = 4, final R = 0.075, Rw = 0.069 for 3283 observed unique reflections. By the comparison with ethyl α - cyano - α - (2-nitrophenyl) acetate, it was studied the influence of steric and electronic effects in molecule to the bond parameters and special spectroscopy information . So was that to the bond parameters and 1H NMR spectroscopy of ethoxy group in molecule.
