A new complex, [Zn2（HL）2（2,5-OH-pbda）]n（1, L = 1-（1 H-imidazol-4-yl）-4-（4 Htetrazol-5-yl）benzene（H2L） and 2,5-OH-H2 pbda = 2,5-dihydroxy-terephthalic acid）, has been hydrothermally prepared and characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis and PXRD. Complex 1 crystallizes in monoclinic, space group P21/n with a = 8.8101（10）, b = 17.105（2）, c = 9.4014（11）A, β = 105.704（2）o, V = 1363.9（3） A3, Z = 4, C（14）H9N6O3Zn, Mr = 374.64, Dc = 1.824 g/cm3, μ = 1.831 mm^（-1）, S = 1.042, F（000） = 756, the final R = 0.0309 and w R = 0.1003 for 3130 observed reflections（I 2σ（I））. The H2L ligand was deprotonated to be an HL-anion, and coordinated with Zn^（2＋） to form two-dimensional（2D） Zn2（HL^-）2^（2＋） sheets, which were pillared by the 2,5-OH-pbda2-ligands to form a three-dimensional（3D） dmc net with Point（Schlafli） symbol of（4·82）（4·85）. The large vacancy of the dmc net is filled via mutual interpenetration of another independent framework, leading to the formation of a 2-fold interpenetrating architecture. Solid state luminescent property of 1 has been investigated.

A new one-dimensional Mg（Ⅱ） coordination polymer, [Mg（L）（phen）（H2O）]（1）, has been hydrothermally synthesized by using 3,5-dinitro-salicylic acid（H2L） and 1,10-phenanthroline（phen）. It crystallizes in monoclinic, space group C2/c with a = 33.038（7）, b = 6.6481（13）, c = 22.750（5） A, β = 126.99（3）°, V = 3991.1（14） A3, Z = 8, C19H12 MgN4O8, Mr = 448.64, Dc = 1.493 g/cm3, F（000） = 1840, μ（Mo Ka） = 0.146 mm-1, R = 0.0559 and w R = 0.0975. In 1, each L anion bridges two Mg（Ⅱ） atoms to give one-dimensional zigzag chains with the Mg…Mg separation of 5.34 ？, which are extended by π-π stacking interactions between 1,10-phenanthroline ligands into a two-dimensional supramolecular layer. Moreover, the O–H…O hydrogen-bonding interactions further stabilize the layer structure of 1. The luminescent property was also studied for 1 in solid state at room temperature. In addition, natural bond orbital（NBO） analysis was performed by the B3LYP/LANL2 DZ method in Gaussian 09 Program. The calculation results show obvious covalent interaction between the coordinated atoms and Mg（Ⅱ） ion.

A new coordination polymer,{[Ag2（bpp）2（H2O）2]·bpdc·3H2O}n,derived from the ligand biphenyl-4,4＇-dicarboxylic acid（H2bpdc）,has been obtained through a hydrothermal technique（bpp = l,3-bis（4-pyridyl）propane）.Its single-crystal structure has been characterized by single-crystal X-ray diffraction,powder XRD,FT-IR,TGA and elemental analysis techniques.The single-crystal X-ray diffraction reveals that complex 1 consists of 1D infinite[Ag（bpp）（H2O）]n^（n＋）cationic chains,2D anionic layer constructed by bpdc anions and free water which provide charge compensation in the crystal structure.The 1D infinite[Ag（bpp）（H2O）]n^（n＋） cationic chains and 2D anionic layer are further stacked in-ABAB- fashion through intermolecular H-bonding to form a 3D sandwich-like framework.In addition,the luminescent property of complex 1 in the solid state at room temperature was investigated.

TiO2-SiO2 hybrid materials containing Eu^3＋ ions were prepared via sol-gel method. Upon the introduction of TiO2, the emission intensity and the average decay time increase, revealing that the incorporation of TiO2 can reduce the extent of the Eu^3＋ clusters. At the same time, the intensity ratio of ^5D0→^7F2 to ^5D0→^7F1 increases as the TiO2 concentration increases, indicating the formation of Eu^3＋ - O^2- - Ti^4＋ bonding. Moreover, the influence of the ion Eu^3 ＋ concentration on the luminescence properties and the R value were investigated.
