One new luminescent material of complex {[Cd(DPA)(H_2O)_2]·(H_2O)_2}_n(1) was synthesized by evaporation methods using 3,3?-thiodipropionic acid(DPA) and cadmium nitrate as the starting materials. Compound 1 crystallizes in the monoclinic system,space group P2_1/n with a = 7.5460(7),b = 13.372(3),c = 12.304(3) ?,β = 95.95(3)o,V = 1234.8(4) ?~3,D_c = 1.940 g/cm~3,C_6H_(16)O_8 SCd,M_r = 360.65,F(000) = 720,μ(Mo Ka) = 1.960 mm~(-1),Z = 4,R = 0.0460 and wR = 0.1185 for 1835 observed reflections(I > 2σ(I)),and R = 0.0591,wR = 0.1245 for all data. The complex has been characterized by elemental analysis,FT-IR,TG,PXRD and X-ray single-crystal structure analysis and the fluorescence property has also been studied. As a result,complex 1 possesses a two-dimensional(2-D) structure through DPA ligands interconnecting Cd2+ ions. Complex 1 emits the intense fluorescence of 420 nm in the solid state at room temperature.
