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.

The compound （H3IDC）（Prz）0.5（H2O） （H3IDC = imidazole-4,5-dicarboxylate, Prz = piperazine） has been prepared from a hydrothermal approach and was characterized by IR analysis and X-ray diffraction. Its crystal structure consists of discrete 4,5-imidazole-dicarboxylate, H2O and piperazine molecules. The whole structural motif was assembled by three different non-covalent interactions of O-H…O, N-H…O and π-π stacking, which play an important role in packing the molecules. Interestingly, the connections between imidazole-4,5-dicarboxylate molecule and water molecule result in a helical polymeric chain.

Self-assembly of Ag(I) nitrate, 1,3-bis(4-pyridyl)propane (bpp) and phthalic acid monopotassium salt (KHphth) in CH3OH-H2O solution produced the title complex, {[Ag(bpp)]2(Hphth)(NO3)·(H2O)2}n, which was characterized by single-crystal X-ray diffraction, elemental analysis, IR spectrum, and photoluminescent spectrum. Single-crystal X-ray analysis revealed that the complex crystallizes in a monoclinic system, space group P21/c, with a = 15.4174(5), b = 8.6398(2), c = 25.2466(8) , β = 91.072(1)o, V = 3362.34(17) 3, Z = 4, C34H37N5O9Ag2, Mr = 875.43, Dc = 1.729 g/cm3, μ = 1.228 mm-1, F(000) = 1768, the final R = 0.0749 and wR = 0.1580 for 5754 reflections with I > 2σ(I).

The Hphth- and nitrate counter-ions are bridged by solvent water molecules through hydrogen bonds to generate a one-dimensional chain extending along the b axis. Electrostatic interactions between cations and anions, extensive hydrogen bonds and π-π interactions are responsible for the three-dimensional supramolecular structure. In the solid state, the compound exhibits blue photoluminescence with the maximum at 436 nm upon excitation at 344 nm.

The two Tb(Ⅲ) ions are linked by four carboxylate groups through their bidentate bridging modes, forming a dimeric unit with crystallographic inversion center. Each terbium ion has an eight-coordinate geometry with four of the coordination sites occupied by four oxygen atoms from the four bridging carboxylates, respectively, two oxygen atoms from bidentate carboxylate, and the remaining positions occupied by two nitrogen atoms from a 1,10-phenanthroline molecule. The Tb(Ⅲ) ion adopt a distorted square antiprism coordination geometry. The excitation and luminescence data observed at room temperature show that the title complex emits very intensive green fluorescence under ultraviolet light. The result of thermal analysis indicates the complex [Tb(p-ClBA)_3phen]_2 is quite stable to heat. CCDC: 221921.
