A one-dimensional ladder-type coordination polymer, poly[[(μ2-hydroxido)(μ2-1H-pyrazole-3,5-dicarboxylato)gallium(III)] monohydrate], [Ga(C5H2N2O4)(OH)(H2O)] n or [Ga(HPDC)(OH)(H2O)] n , I, isotypic with a V3+ coordination polymer previously reported by Chen et al. [J. Coord. Chem. (2008). 61, 3556–3567] was prepared from Ga3+ and pyrazole-3,5-dicarboxylic acid monohydrate (H3PDC·H2O). Compound I was isolated using three distinct experimental methods: hydrothermal (HT), microwave-assisted (MWAS) and one-pot (OP) and the crystallite size should be fine-tuned according to the method employed. The coordination polymeric structure is based on a dimeric Ga3+ moiety comprising two μ2-bridging hydroxide groups, which are interconnected by HPDC2− anionic organic linkers. The close packing of individual polymers is strongly directed by the supramolecular interactions, namely several O—H...O and N—H...O hydrogen-bonding interactions.

(Aqua)O—H...N hydrogen-bonding interactions induce the formation of one-dimensional helical [Zn(L)(bpmb)(H2O)]nchains which are interlinked through (aqua)O—H...O hydrogen-bonding interactions, producing two-dimensional corrugated sheets.

Form Part

The title compound, {[Zn4(C8H4O4)3(OH)2(C12H6N2O2)2]·2H2O}n, has been prepared hydrothermally by the reaction of Zn(NO3)2·6H2O with benzene-1,4-dicarboxylic acid (H2bdc) and 1,10-phenanthroline-5,6-dione (pdon) in H2O. In the crystal structure, a tetranuclear Zn4(OH)2fragment is located on a crystallographic inversion centre which relates two subunits, each containing a [ZnN2O4] octahedron and a [ZnO4] tetrahedron bridged by a μ3-OH group. The pdon ligand chelates to zinc through its two N atoms to form part of the [ZnN2O4] octahedron. The two crystallographically independent bdc2−ligands are fully deprotonated and adopt μ3-κO:κO′:κO′′ and μ4-κO:κO′:κO′′:κO′′′ coordination modes, bridging three or four ZnIIcations, respectively, from two Zn4(OH)2units. The Zn4(OH)2fragment connects six neighbouring tetranuclear units through four μ3-bdc2−and two μ4-bdc2−ligands, forming a three-dimensional framework with uninodal 6-connected α-Po topology, in which the tetranuclear Zn4(OH)2units are considered as 6-connected nodes and the bdc2−ligands act as linkers. The uncoordinated water molecules are located on opposite sides of the Zn4(OH)2unit and are connected to it through hydrogen-bonding interactions involving hydroxide and carboxylate groups. The structure is further stabilized by extensive π–π interactions between the pdon and μ4-bdc2−ligands.

New Compounds

New compounds and coordination polymers with highly polarizable metals (M = Hg, Pb) and 2,2′;6′2′-terpyridine (terpy) and 2,6-bis(benzimidazol-2-yl)pyridine (bbp) ligands have been synthesized and characterized for their photo-physical and optical properties. Hg(L)(CN)2 (L = terpy, bbp) exhibit π-stacking interactions, which form a supramolecular alignment of the planar terpy and bbp units. Pb(terpy)X2[Hg(CN)2]0.5 (X = Cl, Br) generate one-dimensional coordination polymers through bridging Hg(CN)2 linkers and hydrogen-bonding interactions. All of the metal centres have very distorted coordination geometries. Hg(L)(CN)2 (L = terpy, bbp) and Pb(terpy)Br2[Hg(CN)2]0.5 show terpy or bbp based emission. The materials are very birefringent, with Δn ranging from 0.37(2) to 0.45(2). The magnitude of the observed birefringence depends on the orientation of the highly polarizable terpy and bbp units in relation to the viewing axis of the crystals. These materials represent rare examples of multifunctional emissive and birefringent systems.

In the crystal structure, the pyridine-2,3-dicarboxylate (pydc2−) ligand exhibits μ3-η1,η1:η1:η1and μ3-η1,η1:η1,η1:η1coordination modes, bridging two FeIIIcations and one SrIIcation. The SrIIcation, which is located on an inversion centre, is eight-coordinated by six O atoms of four pydc2−ligands and two water molecules. The coordination geometry of the SrIIcation can be best described as distorted dodecahedral. The FeIIIcation is six-coordinated by O and N atoms of four pydc2−ligands in a slightly distorted octahedral geometry. Each FeIIIcation bridges two neighbouring FeIIIcations to form a one-dimensional [Fe2(pydc)4]nchain. The chains are connected by SrIIcations to form a three-dimensional framework. The topology type of this framework istfj. The structure displays O—H...O and C—H...O hydrogen bonding.

A novel manganese coordination polymer, poly[(μ5-thiophene-3,4-dicarboxylato)manganese(II)], [Mn(C6H2O4S)]n, was synthesized hydrothermally using 3,4-thiophenedicarboxylate (3,4-tdc2−) as the organic linker. The asymmetric unit of the complex contains an Mn2+cation and one half of a deprotonated 3,4-tdc2−anion, both residing on a twofold axis. Each Mn2+centre is six-coordinated by O atoms of bridging/chelating carboxylate groups from five 3,4-tdc2−anions, forming a slightly distorted octahedron. The Mn2+centres are bridged by 3,4-tdc2−anions to give an infinite two-dimensional layer which incorporates one-dimensional Mn–O gridlike chains, and in which the 3,4-tdc2−anion adopts a novel hexadentate chelating and μ5-bridging coordination mode. The fully deprotonated 3,4-tdc2−anion exhibits unexpected efficiency as a ligand towards the Mn2+centres, which it coordinates through all of its carboxylate O atoms to provide the novel coordination mode. The IR spectrum of the complex is also reported.

The reaction of 4,4′-bipyridine with copper acetate in the presence of 4-nitrophenol led to the formation of the title compound, {[Cu(CH3COO)2(C10H8N2)]·C6H5NO3·2H2O}n. The complex forms a double-stranded ladder-like coordination polymer extending along thebaxis. The double-stranded polymers are separated by 4-nitrophenol and water solvent molecules. The two CuIIcentres of the centrosymmetric Cu2O2ladder rungs have square-pyramidal coordination environments, which are formed by two acetate O atoms and two 4,4′-bipyridine N atoms in the basal plane and another acetate O atom at the apex. The ladder-like double strands are separated from each other by one unit-cell length along thecaxis, and are connected by the water and 4-nitrophenol molecules through a series of O—H...O and C—H...O hydrogen-bonding interactions and two unique intermolecular π–π interactions.
