Abstract: The title complex[Eu2C40H46N6O8·2(NO3)] was prepared and characterized by X-ray diffraction. The Ligand is dischiff base from ovanillin and diethylenetriamine. The complex crystallizes in monoclinic system, space P21/c, a=1.6546(3)nm, b=1.6519(3) nm, c=1.5807(3) nm, β =91.81(3), V=4.318(2)nm3, Dx=1.795Mg·m-3, z=4, =2.9557mm-1, F(000)=2320, the final R=0.058, Rw=0.076. In the complex the coordination number of Eu(Ⅲ) is 8 with a geometry of bicapped trigonal prism. The coordination atoms are oxygen atoms and nitrogen atoms.
