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), β=111.931(1)o, V=5438.65(14)3, Z=4, C46H52N6O25S2Tb2, Mr=1470.90, Dc=1.796 g/cm3, μ=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.
