Heterometallic Polymer

A new 3d–4fheterometallic polymer, poly[[aqua-μ3-chlorido-[μ3-4-(pyridin-4-yl)benzoato]tris[μ2-4-(pyridin-4-yl)benzoato]dicopper(I)erbium(III)] dihydrate], {[Cu2Er(C12H8NO2)4Cl(H2O)]·2H2O}n, was synthesized by the hydrothermal reaction of Er2O3, CuCl2·2H2O and 4-(pyridin-4-yl)benzoic acid in the presence of HClO4. The asymmetric unit contains one Er3+cation, two Cu+cations, one Cl−anion, four deprotonated 4-(pyridin-4-yl)benzoate ligands, one coordinated aqua ligand and two solvent water molecules. This tubular one-dimensional polymer is constructed from alternating clusters of europium(III)–water and copper(I) chloride bridged by 4-(pyridin-4-yl)benzoate ligands. Extensive hydrogen-bonding interactions involving both the coordinated and the solvent water molecules provide further stabilization to the structure.

The title compound, {[Ag(C6H7AsNO3)(C18H15P)]·H2O}n, has been synthesized from the reaction of 4-aminophenylarsonic acid with silver nitrate, in aqueous ammonia, with the addition of triphenylphosphane (PPh3). The AgIcentre is four-coordinated by one amino N atom, one PPh3P atom and two arsonate O atoms, forming a severely distorted [AgNPO2] tetrahedron. Two AgI-centred tetrahedra are held together to produce a dinuclear [Ag2O2N2P2] unit by sharing an O–O edge. 4-Aminophenylarsonate (Hapa−) adopts a μ3-κ3N:O:O-tridentate coordination mode connecting two dinuclear units, resulting in a neutral [Ag(Hapa)(PPh3)]nlayer lying parallel to the (10\overline{1}) plane. The PPh3ligands are suspended on both sides of the [Ag(Hapa)(PPh3)]nlayer, displaying up and down orientations. There is anR22(8) hydrogen-bonded dimer involving two arsonate groups from two Hapa−ligands related by a centre of inversion. Additionally, there are hydrogen-bonding interactions involving the solvent water molecules and the arsonate and amine groups of the Hapa−ligands, and weak π–π stacking interactions within the [Ag(Hapa)(PPh3)]nlayer. These two-dimensional layers are further assembled by weak van der Waals interactions to form the final architecture.

The asymmetric unit of the title coordination polymer, [Co(C9H4N2O4)(C2H4N4)] n or [Co(L 1)(L 2)] n , consists of one crystallographically independent Co2+ centre, one L 1 2− ligand and one L 2 ligand (L 1 = 1H-benzimidazole-5,6-dicarboxylic acid, L 2 = 3-amino-1,2,4-triazole). The Co2+ centre is coordinated by two carboxylato-O atoms from two independent L 1 2− ligands and two nitrogen atoms from L 2 and another L 1 ligand. Thus, the metal center adopts a four-coordinate mode, forming a tetrahedral geometry. Interestingly, through the combination of two L 1 2−, two L 2 ligands and two Co2+ ions, a basic repeating unit is constructed, resulting in the formation of a one-dimensional straight chain structure. These chains are further expanded to the final three-dimensional framework via N—H...O hydrogen-bonding interactions.

Trigonal Prismatic

The asymmetric unit of the title compound, [Ag3Yb(C5HN2O4)2(H2O)2]n, contains three AgIions, one YbIIIion, two imidazole-4,5-dicarboxylate ligands and two coordinating water molecules. The YbIIIatom is eight-coordinated, in a bicapped trigonal prismatic coordination geometry, by six O atoms from three imidazole-4,5-dicarboxylate ligands and two coordinating water molecules. The two-coordinated AgIions exhibit three types of coordination environments. One AgIatom is bonded to two N atoms from two different imidazole-4,5-dicarboxylate ligands. The other two AgIatoms are each coordinated by one O atom and one N atom from two different imidazole-4,5-dicarboxylate ligands. These metal coordination units are connected by bridging imidazole-4,5-dicarboxylate ligands, generating a two-dimensional heterometallic layer. These layers are stacked along theaaxisviaO—H...O hydrogen-bonding interactions to generate a three-dimensional framework.

The structures of two hydrated salts of 4-aminophenylarsonic acid (p-arsanilic acid), namely ammonium 4-aminophenylarsonate monohydrate, NH4+·C6H7AsNO3−·H2O, (I), and the one-dimensional coordination polymercatena-poly[[(4-aminophenylarsonato-κO)diaquasodium]-μ-aqua], [Na(C6H7AsNO3)(H2O)3]n, (II), have been determined. In the structure of the ammonium salt, (I), the ammonium cations, arsonate anions and water molecules interact through inter-species N—H...O and arsonate and water O—H...O hydrogen bonds, giving the common two-dimensional layers lying parallel to (010). These layers are extended into three dimensions through bridging hydrogen-bonding interactions involving thepara-amine group acting both as a donor and an acceptor. In the structure of the sodium salt, (II), the Na+cation is coordinated by five O-atom donors, one from a single monodentate arsonate ligand, two from monodentate water molecules and two from bridging water molecules, giving a very distorted square-pyramidal coordination environment. The water bridges generate one-dimensional chains extending alongcand extensive interchain O—H...O and N—H...O hydrogen-bonding interactions link these chains, giving an overall three-dimensional structure. The two structures reported here are the first reported examples of salts ofp-arsanilic acid.

The structure of the title hydrated molecular salt, C14H23N2O4+·C2H3O2−·H2O, was determined as part of a wider study on the use of the molecule as a polydentate ligand in the synthesis of MnIIIclusters with magnetic properties. The cation features intramolecular O—H...N and N—H...O hydrogen-bond interactions. The crystal structure features a range of intermolecular hydrogen-bonding interactions, principally O—H...O interactions between all three species in the asymmetric unit. AnR24(8) graph-set hydrogen-bonding motif between the anion and water molecules serves as a unit which links to the cationviathe diethanolamine group. Each O atom of the acetate anion accepts two hydrogen bonds.

Abstract The complexes [Zn(dpa)MoO4] (1) and [Zn(dpa)MoO4]·0.5H2O (20.5H2O) (dpa = 2,2'-dipyrid- ylamine) were synthesized hydrothermally. Single crystal structure analyses indicate that 1 and 2 are conformational isomers. They both consist of binuclear units of edge-sharing {ZnN2O3} trigonal bipyramids bridged by pairs of bidentate briding {MoO4}2- anions into a one-dimensional ribbon, but their orientations of the terminal O atoms of the {MoO4}2- anions are different. In 1 and 2, the ribbon-like chains are connected into a 2D network via hydrogen bonding interactions between the central N-H portions of the dpa molecules and the terminal O atoms of {MoO4} tetrahedra. For 2, in addition, the hydrogen bonding interactions between the crystal water molecules and the terminal O atoms of {MoO4} tetrahedra join the 2D layers into a 3D architecture. They play an important role not only in constructing the 3D architecture, but also in the conformational stability.

The title compound, [Fe2Yb2(CN)12(C4H9NO)5(H2O)6]·2H2O, is a tetranuclear complex, where the four metal centres are connected through three cyano bridges, the iron centres making one and two bridges, respectively. Each Fe atom is surrounded by six cyano ligands, forming almost ideal octahedra. The two Yb atoms have different ligand environments; both are coordinated by seven ligands, consisting of water molecules, dimethylacetamide (DMA) solvent and cyano groups, but not in the same ratio. Four of the five DMA molecules show various degrees of common structural disorder. The asymmetric unit also includes two solvent water molecules, which take part in hydrogen bonding, forming an extended network of tetramers.

A supramolecular compound,catena-poly{[Cu2(1,3-μ2-(1a))2(μ2-ter)2(H2O)2]n·(6H2O)n} (1) has been synthesized using (1a) [(1a=N1,N3,N5-trimethyl-N1,N3,N5-tris((pyridin-4-yl)methyl)-1,3,5-benzene tricarboxamide] and terephthalate (ter) as the pillaring unit by self-assembly. The terephthalate units are connected by copper(II) ions forming a single strand, while a pair of such strands are then linked by (1a)viatwo pyridyl terminal arms bound to copper(II) nodes on either side forming a one-dimensional double stranded assembly propagating along thecaxis. The compound crystallizes in theFdd2 space group. The cavity created in the interior of this double strand assembly trap six water molecules and are stabilized by hydrogen bonding with the host. The arrangement of the pair of acyclic water trimers in isolated cavities of (1) is such that it resembles a closed-bracket-like formation. The Hirshfeld surface analysis of (1) reveals the presence of strong intermolecular hydrogen-bonding interactions between one-dimensional ladder-like units and with the water trimer in the host cavity. The copper(II)-containing coordination polymer also acts as an efficient catalyst for the Glaser–Hay homo-coupling reaction.
