| 摘 要： | The supramolecular terbium complex, {[Tb（SIP）（H2O）5]2（bpy）3（H2O）}n （NaH2SIP = 5-sulfoisophthalic acid monosodium salt and bpy = 4,4＇-bipyridyl）, has been synthesized by the hydrothermal reaction of Tb4O7 with NaH2SIP and bpy at 165 ℃, and characterized by single-crystal X-ray diffraction, elemental analysis, IR spectrum, powder X-ray diffraction and photoluminescence spectrum. It crystallizes in a monoclinic system, space group C2/c, with a = 30.6840（1）, b = 10.9206（2）, c = 17.4967（3） A, β= 111.931（1）°, V = 5438.65（14） A^3, Z = 4, C46H52N6O25S2Tb2, Mr = 1470.90, Dc = 1.796 g/cm^3, p = 2.747 mm^-1, F（000） = 2928, the final R = 0.0654 and wR = 0.1322 for 3806 observed reflections with I 〉 2σ（I）. In the neutral [Tb（SIP）（H2O）5]2 motif, the Tb（III） ions are linked by the SIP ligands to form a one-dimensional zigzag chain propagating along the c axis. The zigzag chains are linked together by hydrogen bonds and π-π stacking interactions to form a two-dimensional supramolecular framework. The uncoordinated bpy molecules act as pillars to extend the two-dimensional sheets into a distinctive pillared three-dimensional supramolecular structure through O-H...N hydrogen bonds. The photoluminescence of the complex was investigated at room temperature in the solid state.
