Abstract: The complexes of Tb (Ⅲ), Y (Ⅲ), Nd (Ⅲ) nitrate with N, N-disalicylideneethylenediamine, dimethyl sulfoxide as the ligands were synthesized. Their molecularcomposition are [RE(C6H5OHCHNC2H4NCHC6H5OH) (NO3)3 (CH3SOCH3)]. The molecularstructures of the complexes were determined by X-ray diffraction. The crystal of Tb (Ⅲ)complex is monoclinic with space group P21/n, a=0.9628 (3) nm, b=1.6439 (4) nm,c=1.6256(2) nm, β=102.78(2), V=2.509(2)nm3, Dx=1.830 g/cm3, Z=4, p=2. 996mm-1, F (000)=1638, R=0. 043, Rw=0. 046. The coordination number of Tb (Ⅲ) is 9 with the geometry of a monocapped square antiprism. All of coordination atoms are oxygenatoms. The two central ions were bridged by the two Schiff base, resulting in an infinitechain.
