Two new CuII coordination polymers, namely [Cu2(BDC)2(L)4 (H2O)2]•14H2O(1) and [Cu1.5(BTC)(L)1.5(H2O)0.5] • 2H2O( 2), where L = 1,1’-(1,4-butanediyl)bis(imidazole), BDC = 1,4- benzenedicarboxylate, and BTC = 1,3,5-benzenetricarboxylate, have been synthesized at room temperature. Complex 1 exhibits an unusual, square-planar, four-connected 2D 264 net, which has been predicated by Wells. Interestingly, three types of water clusters, namely (H2O)6,( H2O)8, and (H2O)10, are observed in the hydrogen-bonded layers constructed by the BDC ligands and water molecules. The BTC anion in compound 2 is coordinated to the CuII cation as tetradentate ligand to form a (66)2(426484)2(64810) net containing three kinds of nonequivalent points. Thermogravimetric analyses (TGA) and IR spectra for 1 and 2 are also discussed in detail.

The reactions of AgNO3 with Na2L and Mg(HL)2 (H2L =5-sulfosalicylic acid) gave two luminescent coordination polymers: Ag2L(H2O) (1) and [Ag2(HL)2(H2O)3]H2O(2), respectively. 1 crystallizes in the monoclinic space group P2/n, with a = 7.489(2), b = 16.237(3), c = 8.222(2) Å , β= 92.90(3)°, V = 998.5(3) Å3, Z = 4. Compound 1 is the first silver carboxylate-sulfonate with an extended three-dimensional structure, a framework composed of four kinds of crystallographically unique silver atoms and organic species with three different functional groups, carboxylic, hydroxyl, and sulfonic, each coordinated to the silver atoms. 2 crystallizes in the triclinic space group Pī, with a = 8.307(2), b = 11.246(2), c = 12.590(3) Å, α = 112.68(3), β = 97.66(3), γ = 95.51(3)°, V = 1061.6(4) Å3, Z = 2. In 2, silver ions are bridged by sulfonate groups to form one-dimensional chains, and each chain is connected to the two neighboring chains through the coordination of the carbonyl oxygen atoms to the silver ions of the neighboring polymeric chain to form a two-dimensional network. The luminescent properties of the two compounds are also discussed.

Using lowtemperature hydrothermal methods, nanoscale lanthanide phenylphosphonates species with different morphologies, namely, nanoparticles and nanorods, have been systematically synthesized. The possible growth mechanism of these nanorods was discussed. Xraydiffraction, transmissionelectronmicroscopy, electrondiffraction, and photoluminescence spectra were used to characterize these materials. The photoluminescent properties of Eu(O3PC6H5) (HO3PC6H5) and La0.91Eu0.09(O3PC6H5) (HO3PC6H5) nanorods were discussed.

In this paper, four novel silver(I) sulfonate coordination polymers containing neutral ligands, namely, [Ag2L1(biim)2] • 2H2O( 1), AgL2(biim) (2), [Ag(HL3)(Pic)2] • H2O( 3), and [Ag3(L3)(HL3)(4,4’-bipy)3(H2O)2] • 4H2O( 4), have been synthesized [L1 = 3-carboxy-4-hydroxybenzenesulfonate, L2 = p-aminobenzenesulfonate, H2L3 ) p-hydroxybenzenesulfonic acid, biim ) 1,1’-(1,4-butanediyl)-bis(imidazole),Pic =β-picoline,4,4‘-bipy = 4,4’-bipyridine].For compounds1 and 2, Ag(I) cationsare bridged by biim ligands to form a one-dimensional (1D) “zigzag” chain, and L1 and L2 sulfonate ligands are not coordinated to the silver cation. Compound 3 has a dimeric structure in which two silver cations are bridged by two HL3 ligands. For compound 4, L3 ligand coordinates to a silver cation as a monodentate ligand, and Ag(I) cations are bridged by 4,4’-bipy ligands to form a 1D chain. Compound 1 contains water dimers, while compound 4 contains water trimers. Compounds 1-3 display room-temperature photoluminescence.
