In the title coordination polymer, {[Ba(C8H5Cl2O3)2(H2O)].H2O}n, each Ba(II) atom is nine-coordinated by six carboxylate O atoms and one ether O atom from five symmetry-related 2,4-dichlorophenoxyacetate ligands, and by two O atoms from water molecules, thus defining a distorted tricapped trigonal prism. The Ba(II) ions are bridged by bidentate water molecules and by tridentate and tetradentate 2,4-dichlorophenoxyacetate groups, leading to a two-dimensional layer structure. The crystal structure is further stabilized by hydrogen-bonding interactions within each layer.

In the title coordination polymer, [Cd2(SO4)2(C13H8N4)(H2O)2]n, there are two crystallographically independent Cd(II) centres with different coordination geometries. The first Cd(II) centre is hexacoordinated by four O atoms of four sulfate ligands, one water O atom and one N atom of a 1H-imidazo[4,5-f][1,10]phenanthroline (IP) ligand, giving a distorted octahedral coordination environment. The second Cd(II) centre is heptacoordinated by four O atoms of three sulfate ligands, one water O atom and two N atoms of one chelating IP ligand, resulting in a distorted monocapped anti-trigonal prismatic geometry. The symmetry-independent Cd(II) ions are bridged in an alternating fashion by sulfate ligands, forming one-dimensional ladder-like chains which are connected through the IP ligands to form two-dimensional layers. These two-dimensional layers are linked by interlayer hydrogen bonds, leading to the formation of a three-dimensional supramolecular network.

The macro-synthetic fiber is widely used to prevent the cracking at concrete members. By the way of experiment that macro-synthetic fiber-reinforced concrete ductile columns comparing with the usual fiber-reinforced columns under the action of low-frequency cyclic loading, seismic performance of the columns in different form of bars were obtained. Meanwhile, the damage pattern, hysteresis curve, ductile coefficient and equivalent viscous damping coefficient of the columns could be also obtained. The results show that the macro-synthetic fiber-reinforced concrete ductile column has the better ductility and the higher post-crack energy absorption ability.

A novel complex of [Ag (bib)(3-pySO3)] n (3-pySO3:3-pyridinesulfonate; bib 1, 4-bis (2-methyl-imidazol-1-yl) butane) was synthesized and characterized by elemental analysis, IR, X-ray single crystal diffraction. The title complex belongs to triclinic system with space group P-1, a=7.8030(16)Å, b=8.0070(16)Å, c=10.742(2)Å,α=84.64(3)°,β=82.33(3)°,γ=82.76(3)°, V=657.8(2)Å3, Z=2, Dc=1.894g/cm3, μ= 1.697mm-1, F(000)= 374. Final indices is R =0.0480, wR =0.1169. Thermal stability and luminescent property of compound have also been investigated.

One new organic-inorganic hybrid materials of complex Ag 2 ClO 5 N 5 C 28 H 22 (1) was synthesized by evaporation methods using 2-Chlorobenzeneacetic acid(2-CBAA), 4,4'-dipyridyl (4,4'-bipy), and AgNO 3 . And the complex was characterized by elemental analysis, FT-IR, thermogravimetrie analysis(TGA), XRD, X-ray single-crystal structure analysis and fluorescence properties have been studied. As a result, complex 1 are one-dimensional structure. Among others, Ag(I) ion is surrounded by two nitrogen atoms from two bipy ligands form an infinite chain, and adjacent Ag-bipy chains produce "rungs" of a ladder by silver ions contacts. Complex 1 emits the intensely luminescence with the fluorescence of 486 nm in a solid state at room temperature. CCDC: 1031206.
