| 摘 要： | A new coordination compound with formula Tb（2-TC）3（DMF）]n （1, 2-TC = 2-thio- phenecarboxylic ligand and DMF = dimethylformamide） was synthesized by solvothermal method. The structure of compound 1 was determined by single-crystal X-ray diffraction analyses, and characterized by elemental analyses, IR and powder X-ray diffraction. Structure analysis reveals compound 1, exhibiting a one-dimensional chain structure, crystallizes in triclinic space group P21/c, with a = 9.2751（19）, b = 16.490（3）, c = 15.865（5） A, β = 118.98（2）°, V= 2122.7（9）A3, D,. = 1.916 g/cm3, Mr= 612.45 （C18H15NO7S3Tb）, F（000） = 1196,μ（MoKa） = 3.67 mm-1, Z = 4, R = 0.0616 and wR = 0.0962 for 3865 observed reflections （I 〉 2o（I））, and R = 0.1092 for all data. Meanwhile, the photoluminescent properties of compound 1 were also investigated in the solid state at room temperature.
