Two-dimensional metal-organic framework constructed from 4,4'-bipydine and 1,2,4-benzenetricarboxylate: Synthesis, structure and magnetic properties
Abstract
Two new copper coordination polymers generated from mixed organic ligands 4,4'-bipydine and 1,2,4-benzenetricarboxylate [Cu{sub 3}(1,2,4-BTC){sub 2}(4,4'-bipy)(H{sub 2}O){sub 4}] 1 and [Cu(1,2,4-HBTC)(4,4'-bipy)] 2 (1,2,4-BTC=1,2,4-benzenetricarboxylate) have been prepared hydrothermally and characterized by single crystal X-ray diffraction. Compound 1 crystallizes in the noncentrosymmetric space group Fdd2, with a=19.004(3)A, b=26.711(4)A, c=11.0770(15)A, V=5622.8(14)A{sup 3}, and Z=8. Its structure contains two different one-dimensional (1-D) chains for the Cu ions, namely [Cu{sub 2}(1,2,4-BTC){sub 2}]{sub n}{sup 2n-} and [Cu(4,4{sup '}-bipy)]{sub n}{sup 2n+}; the carboxylate of 1,2,4-BTC ligands links the two different 1-D chains into an interesting steplike neutral framework. Compound 2 crystallizes in the monoclinic space group P2{sub 1}/n, with a=9.9806(8), b=16.5512(16), c=11.3109(7)A, {beta}=99.375(5){sup o}, V=1843.5(3)A{sup 3}, Z=4. Its structure contains novel paddle-wheel clusters Cu{sub 2}(CO{sub 2}){sub 4}(4,4'-bipy){sub 2} as SBUs which are further linked by monoprotonated 1,2,4-BTC ligands into a 2-D neutral framework. The magnetic behaviors of both compounds have been studied.

A 3-connected dia-f-type metal-organic framework compound {l_brace}[Ag(L){sub 3/2}H{sub 2}PO{sub 4}]{r_brace}{sub n} (1) has been synthesized by self-assembly of 4,4'-H{sub 2}bpz (L=4,4'-H{sub 2}bpz=3,3',5,5'-tetramethyl-4,4'-bipyrazole) and Ag{sub 4}P{sub 2}O{sub 7} under hydrothermal conditions. It crystallizes in the tetragonal space group I4{sub 1}/acd with a=21.406(4) A, b=21.406(4) A, c=36.298(8) A, Z=32. X-ray single-crystal diffraction reveals that 1 has a three-dimensional framework with an unprecedented alternate left- and right-handed helices structure, featuring a non-uniform two-fold interpenetrated (4.14{sup 2}) net. Photoluminescent investigation reveals that the title compound displays interesting emissions in a wide region, which shows that the title compound may be a good potential candidatemore »

A three-dimensional porous metal-organic framework constructed from two-dimensional sheets via interdigitation exhibiting dynamic features.
A three-dimensional porous metal-organic framework (PCN-18) was constructed through interdigitating two-dimensional grid sheets composed of 4,4{prime}-(anthracene-9,10-diyl)dibenzoate and copper paddlewheel secondary building units, and its dynamic features were evidenced by gas sorption isotherms. -
Microporous metal organic framework [M{sub 2}(hfipbb){sub 2}(ted)] (M=Zn, Co; H{sub 2}hfipbb=4,4-(hexafluoroisopropylidene)-bis(benzoic acid); ted=triethylenediamine): Synthesis, structure analysis, pore characterization, small gas adsorption and CO{sub 2}/N{sub 2} separation properties
Carbon dioxide is a greenhouse gas that is a major contributor to global warming. Developing methods that can effectively capture CO{sub 2} is the key to reduce its emission to the atmosphere. Recent research shows that microporous metal organic frameworks (MOFs) are emerging as a promising family of adsorbents that may be promising for use in adsorption based capture and separation of CO{sub 2} from power plant waste gases. In this work we report the synthesis, crystal structure analysis and pore characterization of two microporous MOF structures, [M{sub 2}(hfipbb){sub 2}(ted)] (M=Zn (1), Co (2); H{sub 2}hfipbb=4,4-(hexafluoroisopropylidene)-bis(benzoic acid); ted=triethylenediamine).

[Cu{sub 4}OCl{sub 6}(DABCO){sub 2}].0.5DABCO.4CH{sub 3}OH ('MFU-5'): Modular synthesis of a zeolite-like metal-organic framework constructed from tetrahedral {l_brace}Cu{sub 4}OCl{sub 6}{r_brace} secondary building units and linear organic linkers
A novel metal-organic framework (MOF) based on a tetranuclear copper cluster and a linear organic ligand formulated as [Cu{sub 4}OCl{sub 6}(DABCO){sub 2}].0.5DABCO.4CH{sub 3}OH (denoted as MFU-5, MFU=Metal-Organic Framework, Ulm University; DABCO=1,4-diazabicyclo[2.2.2]octane), was prepared via solvothermal synthesis. In contrast with common MOF synthesis strategies, MFU-5 is assembled from pre-defined molecular secondary building units, i.e. {l_brace}Cu{sub 4}OCl{sub 6}{r_brace} moieties, which become the nodes of the coordination framework. The title compound was characterized by single crystal X-ray diffraction, variable temperature powder diffraction (VT-XRPD), thermal analysis, as well as IR- and UV/Vis spectroscopy. Crystal data for MFU-5: hexagonal, P6/mcc (no. 192), a=25.645(9), c=17.105(11) A,more »
