摘要：
The reaction of M(NO_3)_2·6H_2O (M=Cd, Zn), isophthalic acid(H_2IP) as well as 1,4-bis(4-methyl-imidazolyl) benzene(BMIB) results in formation of a 1D complex {[Cd(BMIB)(H_2O)_2](NO_3)_2}_n (1) and 3D complex {[Zn_2(BMIB)_(1.5) (OH)(IP)_(1.5)]·H_2O}_n (2). X-ray diffraction crystal structure analysis shows that 1 crystallizes in triclinic system, space group P1 with a=0.3820 8(3) nm, b=0.904 72(7) nm, c=1.378 29(10) nm, α=98.581(4)°, β=97.020(3)°, γ=94.398(3)°. In 1, BMIB links all the Cd atoms into a 1D chain, which forms 2D bilayer through the H-bond interactions. The complex 2 crystallizes in monoclinic system, space group C2/c with a=3.764 07(9) nm, b=1.017 18(5) nm, c= 2.015 31(11) nm, β=120.860(2)°. On the other hand, in 2, the carboxylate group of ligand IP~(2-) with μ_2-η~1:η~1 coordination mode links metal atoms to give a 1D double-chain structure, which forms 3D network through Zn-N and Zn- OH interactions. In addition, the fluorescence property of complexes 1 and 2 have been investigated, which exhibit good fluorescence in the solid state at room temperature.

摘要：
A new 1D copper(II) polymer [Cu(Hpt)(3,5-DMBA)]_n has been hydrothermally synthesized with copper acetate, 3-(pyridin-2-yl)-1,2,4-triazole(Hpt) and 3,5-dimethylbenzoic acid (3,5-DMBA). It crystallizes in triclinic space group P1, with a = 8.1974(6), b = 8.3280(6), c = 12.5021(9) A, α = 84.3320(10), β = 71.8870(10), γ= 65.4560(10)o, V = 737.44(9) A~3, D_c = 1.612 g/cm~3, Z = 2, F(000) = 366, GOOF = 1.035, R = 0.0298 and wR = 0.0855. The crystal structure is a one-dimensional (1-D) chain in which the Cu(II) is five-coordinated with square pyramidal geometry. The crystal structure shows that the whole molecule consists of two copper ions bridged by two μ_2-η~1:η~0-3,5-dimethylbenzoic acid anions and two 3-(pyridin-2-yl)-1,2,4-triazole molecules. The coordination environment of Cu(II) ion is CuO_2N_3. The luminescence and thermal properties of the complex were investigated.

摘要：
A new radical-mediated method for the synthesis of 1-(2-(1,2-diarylvinyl)phenyl)ethan-1-ones by the redox hydroarylation of o-(hydroxyalkyl)arylalkynes with arylsulfonyl chlorides is described. This visible light catalysis method proceeds via a sequence of the radical addition of aryl group across the C-C triple bond, protonation and redox reaction, and represents a new redox transformation reaction directed by a neighboring hydroxyl group.
