In the title mixed-ligand metal–organic polymeric complex [Cd(C14H8O6S)(C16H16N2)(H2O)]n, the asymmetric unit contains a crystallographically unique CdIIatom, one doubly deprotonated 4,4′-sulfonyldibenzoic acid ligand (H2SDBA), one 3,4,7,8-tetramethyl-1,10-phenanthroline (TMPHEN) molecule and one water molecule. Each CdIIcentre is coordinated by two N atoms from the chelating TMPHEN ligand, three O atoms from monodentate carboxylate groups of three different SDBA2−ligands and one O atom from a coordinated water molecule, giving a distorted CdN2O4octahedral geometry. Single-crystal X-ray diffraction analysis reveals that the compound is a one-dimensional double-chain polymer containing 28-membered rings based on Cd2O2clusters, with a Cd...Cd separation of 3.6889 (4) Å. These chains are linked by O—H...O and C—H...O hydrogen bonds to form a three-dimensional supramolecular framework. The framework is reinforced by π–π and C—O...π interactions.

A new one-dimensional NiIIcoordination polymer of 1,3,5-tris(imidazol-1-ylmethyl)benzene, namelycatena-poly[[aqua(sulfato-κO)hemi(μ-ethane-1,2-diol-κ2O:O′)[μ3-1,3,5-tris(1H-imidazol-1-ylmethyl)benzene-κ3N3,N3′,N3′′]nickel(II)] ethane-1,2-diol monosolvate monohydrate], {[Ni(SO4)(C18H18N6)(C2H6O2)0.5(H2O)]·C2H6O2·H2O}n, was synthesized and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. The NiIIcation is coordinated by three N atoms of three different 1,3,5-tris(imidazol-1-ylmethyl)benzene ligands, one O atom of an ethane-1,2-diol molecule, by a sulfate anion and a water molecule, forming a distorted octahedral NiN3O3coordination geometry. The tripodal 1,3,5-tris(imidazol-1-ylmethyl)benzene ligands link the NiIIcations, generating metal–organic chains running along the [100] direction. Adjacent chains are further connected by O—H...O hydrogen bonds, resulting in a two-dimensional supermolecular architecture running parallel to the (001) plane. Another water molecule and a second ethane-1,2-diol molecule are non-coordinating and are linked to the coordinating sulfate ionsviaO—H...O hydrogen bonds.

NiII MOF (I) shows a 4-connected 3D framework with point symbol 66, but is not a typical dia network. ZnII MOF (II) displays a two-dimensional 44-sql network with one-dimensional water chains penetrating the grids along the c direction. The solid-state photoluminescence analysis of (II) was performed at room temperature and the MOF exhibits highly selective sensing toward Fe3+ and Cr2O7 2− ions in aqueous solution.

Ligands based on polycarboxylic acids are excellent building blocks for the construction of coordination polymers; they may bind to a variety of metal ions and form clusters, as well as extended chain or network structures. Among these building blocks, biphenyltetracarboxylic acids (H4bpta) withC2symmetry have recently attracted attention because of their variable bridging and multidentate chelating modes. The new luminescent three-dimensional coordination polymer poly[(μ5-1,1′-biphenyl-2,2′,4,4′-tetracarboxylato)bis[μ2-1,4-bis(1H-imidazol-1-yl)benzene]dizinc(II)], [Zn2(C16H6O8)(C12H10N4)]n, was synthesized solvothermally and characterized by single-crystal X-ray diffraction, elemental analysis and IR spectroscopy. The crystal structure contains two crystallographically independent ZnIIcations. Both metal cations are located on twofold axes and display distorted tetrahedral coordination geometries. Neighbouring ZnIIcentres are bridged by carboxylate groups in thesyn–antimode to form one-dimensional chains. Adjacent chains are linked through 1,1′-biphenyl-2,2′,4,4′-tetracarboxylate and 1,4-bis(1H-imidazol-1-yl)benzene ligands to form a three-dimensional network. In the solid state, the compound exhibits blue photoluminescence and represents a promising candidate for a thermally stable and solvent-resistant blue fluorescent material.

AbstractThe use of X-ray powder diffraction for the structure determination of inorganic, organic and metal-organic compounds has grown impressively over the last ten years. In supramolecular chemistry, the knowledge of the three-dimensional structure of a material is essential for the discussion of its macroscopic behaviour, and as a result the design of new functionalized materials.TheThe reaction of pyrazine-2,5-dimethyl-3,6-dicarboxylic acid with first row transition metal salts lead to the formation of coordination polymers always in the form of microcrystalline powders. With manganese and nickel salts isostructural 1D coordination polymers were obtained. With zinc chloride and copper chloride isomorphous 1D coordination polymers were obtained. The thermal decomposition of the nickel and copper polymers were studied and it was shown that on the loss of the coordinated water molecules new 3D coordination polymers could be obtained. In both the 1D and 3D coordination polymers the metal atoms have octahedral geometry in N

The asymmetric unit in the structure of the title compound, [K2(C9H4O9S)(H2O)2]n, consists of two eight-coordinated KIcations, one 2,4-dicarboxy-5-sulfonatobenzoate dianion (H2SBTC2−), one bridging water molecule and one terminal coordinated water molecule. One KIcation is coordinated by three carboxylate O atoms and three sulfonate O atoms from four H2SBTC2−ligands and by two bridging water molecules. The second KIcation is coordinated by four sulfonate O atoms and three carboxylate O atoms from five H2SBTC2−ligands and by one terminal coordinated water molecule. The KIcations are linked by sulfonate groups to give a one-dimensional inorganic chain with cage-like K4(SO3)2repeat units. These one-dimensional chains are bridged by one of the carboxylic acid groups of the H2SBTC2−ligand to form a two-dimensional layer, and these layers are further linked by the remaining carboxylate groups and the benzene rings of the H2SBTC2−ligands to generate a three-dimensional framework. The compound displays a photoluminescent emission at 460 nm upon excitation at 358 nm. In addition, the thermal stability of the title compound has been studied.

Five trans-1,4-cyclohexanedicarboxylate (chdc2−) metal–organic frameworks of transition metals were synthesized in aqueous systems. A careful control of pH, reaction temperature and solvent composition were shown to direct the crystallization of a particular compound. Isostructural [Co(H2O)4(chdc)]n (1) and [Fe(H2O)4(chdc)]n (2) consist of one-dimensional hydrogen-bonded chains. Compounds [Cd(H2O)(chdc)]n∙0.5nCH3CN (3), [Mn4(H2O)3(chdc)4]n (4) and [Mn2(Hchdc)2(chdc)]n (5) possess three-dimensional framework structures. The compounds 1, 4 and 5 were further characterized by magnetochemical analysis, which reveals paramagnetic nature of these compounds. A presence of antiferromagnetic exchange at low temperatures is observed for 5 while the antiferromagnetic coupling in 4 is rather strong, even at ambient conditions. The thermal decompositions of 1, 4 and 5 were investigated and the obtained metal oxide (cubic Co3O4 and MnO) samples were analyzed by X-ray diffraction and scanning electron microscopy.
