The crystal of the title compound (C36H29N3O,Mr = 519.62) has been prepared and structurally determined by X-ray single-crystal diffraction. It crystallizes in triclinic P space group with the crystal cell parameters: a = 12.544(4), b = 14.112(4), c = 17.770(5)? = 96.150(6), = 106.112(5), = 107.156(5)? V = 2825.7(14) 3, Z = 4, Dc = 1.221g/cm3, (MoK? = 0.074 mm-1 , F(000) = 1096,the final R = 0.0747 and wR = 0.1632 for 4713 observed reflections with I >2(I). The E-stereochemistry of the title compound can be confirmed by the result of the X-ray diffraction analysis.
