A helical zinc(II) coordination polymer assembled from 1,3-bis[(pyridin-3-yl)methoxy]benzene and benzene-1,4-dicarboxylic acid.

In catena-poly[[aqua[1,3-bis(pyridine-3-ylmethoxy)benzene-κN]zinc(II)]-μ2-benzene-1,4-dicarboxylato-κ(2)O(1):O(4)], [Zn(C8H4O4)(C18H16N2O2)(H2O)]n, each Zn(II) centre is tetrahedrally coordinated by two O atoms of bridging carboxylate groups from two benzene-1,4-dicarboxylate anions (denoted L(2-)), one O atom from a water molecule and one N atom from a 1,3-bis[(pyridin-3-yl)methoxy]benzene ligand (denoted bpmb). (Aqua)O-H···N hydrogen-bonding interactions induce the formation of one-dimensional helical [Zn(L)(bpmb)(H2O)]n chains which are interlinked through (aqua)O-H···O hydrogen-bonding interactions, producing two-dimensional corrugated sheets.

Three coordination polymers constructed from various polynuclear clusters spaced by 2,2'-azodibenzoic acid: syntheses and fluorescent properties.

Solvothermal reactions of M(OAc)2·2H2O (M = Zn, Cd, Pb) with 2,2'-azodibenzoic acid (H2L) in MeOH-H2O (MeOH = methanol) at 120 °C gave rise to three coordination polymers, [Zn12(μ4-O)3L9]n (1), [CdL(H2O)]n (2) and [Pb3(μ4-O)L2]n (3). Compounds 1-3 are characterized by elemental analysis, IR, powder X-ray diffraction and single-crystal X-ray diffraction. Compound 1 has two similar tetranuclear [Zn4(μ4-O)(μ2-CO2)6] units as nodes and displays an intriguing three-dimensional (3D) 6-connected network with a 4(12)6(3) topology.

A sodalite-type porous metal-organic framework with polyoxometalate templates: adsorption and decomposition of dimethyl methylphosphonate.

A sodalite-type porous metal-organic framework with polyoxometalate templates, H(3)[(Cu(4)Cl)(3)(BTC)(8)](2)[PW(12)O(40)]·(C(4)H(12)N)(6)·3H(2)O (NENU-11; BTC = 1,3,5-benzenetricarboxylate), was obtained by a hydrothermal reaction. As a reasonable candidate for eliminating nerve gas, NENU-11 displays good adsorption behavior for dimethyl methylphosphonate (15.5 molecules per formula unit).

Reactivity of polyoxoniobates in acidic solution: controllable assembly and disassembly based on niobium-substituted germanotungstates.

The reactivity of polyoxoniobates has been studied in acidic solution by grafting niobium onto trivacant Keggin-type germanotungstates. Four niobium-containing compounds were obtained in the course of this study. Cs(6.

Coordination between [H2P2W12O48]12- and antimony(III): synthesis and characterization of sandwich complex derived from the new {P2W13O51} fragment.

A sandwich-type anionic cluster of a new lacunary building block [P(2)W(13)O(51)](14-) has been prepared: [H(6){P(2)W(13)O(51)}(2)Sb(4)](10-) (1) was synthesized in a one-pot self-assembly reaction of [H(2)P(2)W(12)O(48)](12-) with C(4)H(4)KO(7)Sb.0.5H(2)O and characterized by single-crystal X-ray analysis, IR, thermogravimetric analysis, elemental analysis, UV, NMR and electrochemistry.
