Abstract: The crystal structures of the title compound (Ⅰ) and (Ⅱ) have been determined by X-ray diffraction. Crystal data are: C_(17)H_(15)NO_3(Ⅰ), triclinic, α=0.7308(2) nm, b=0.8845(3) nm, c=1.1323(3) nm, α=100.03(2)°, β=104.81(2)°, γ=97.20(2)°, V=0.6856(3) nm, Z=2, R=0.047 and C_(18)H_(17)NO_3(Ⅱ), monoclinic, a=1.1006(3) nm, b=1.1172(2) nm, c=1.4046(3) nm, β=102.78(2)°, V=1.5337(6) nm, Z=4, R=0.055. The molecular conformation is cis form for compound Ⅰ and trans form for compound(Ⅱ).
