In this work, a series of MIL-101-SO3H(x) polymeric materials were prepared and further used for the first time as efficient heterogeneous catalysts for the conversion of fructose-based carbohydrates into 5-ethoxymethylfurfural(EMF) in a renewable mixed solvent system consisting of ethanol and tetrahydrofuran(THF). The influence of –SO3H content on the acidity as well as on the catalytic activity of the porous coordination polymers in EMF production was also studied. High EMF yields of 67.7% and 54.2% could be successively obtained from fructose and inulin in the presence of MIL-101-SO;H(100) at 130 °C for 15 h.The catalyst could be reused for five times without significant loss of its activity and the recovery process was facile and simple. This work provides a new platform by application of porous coordination polymers(PCPs) for the production of the potential liquid fuel molecule EMF from biomass in a sustainable solvent system. 展开更多

Two coordination polymers, namely {[Ni(cpna)(H2biim)(H2O)]·H2O}n (1) and {[Mn(cpna)(H2biim)]·H2O}n (2) (H2cpna = 5-(2'-carboxylphenyl) nicotic acid, H2biim = 2,2'- biimidazole),have been hydrothermally synthesized and characterized by elemental analysis, IR, TG, magnetic properties, and single-crystal X-ray diffraction. Compound 1 exhibits a one- dimensional (1D) step-like chain structure, which further builds a three-dimensional (3D) supramolecular architecture via O–HAAAO and N–HAAAO hydrogen-bonding and π-π stacking interactions. Compound 2 possesses a one-dimensional (1D) double chain structure, which is further assembled into a 3D supramolecular framework by N–HAAAO hydrogen bonding and π-π stacking interactions. Magnetic susceptibility measurement indicates that compound 1 shows a weak antiferromagnetic coupling between the nearest Ni(II) centers, with g = 2.11 and J = –1.87 cm^-1. 展开更多

Two new CdⅡ-based coordination polymers(CPs) with mixed adenine(Hade) nucleobase and 5-nitroisophathalate(nip) ligands, {[Cd(Hade)_(0.5)(H_2O)_2(nip)]·H_2O}n 1 and {[Cd(Hade)(H_2O)_(1.25)(CH_3OH)0.75(nip)]·0.75 CH_3OH·0.5H_2 O}_n 2, were successfully obtained by varying the preparation methods and structurally characterized. Crystal data for 1: monoclinic, C2/c space group with a = 10.5546(6), b = 17.3496(6), c = 16.1198(9) ?, β = 104.2800(10)o, V = 2860.6(2) ?3, Dc = 2.058 g/cm^3, Mr = 443.13, Z = 8, F(000) = 1752, μ = 1.585 mm^(–1), the final R = 0.0394 and wR = 0.1109 for 2285 observed reflections with I > 2σ(I). For 2: triclinic, P1 space group with a = 10.2032(7), b = 10.5098(8), c = 11.0223(8) ?, a = 65.7050(10)o, β = 74.5750(10)o, g = 61.5280(10)o, V = 943.38(12) ?~3, Dc = 1.888 g/cm3, Mr = 536.24, Z = 2, F(000) = 537, μ = 1.225 mm^(–1), the final R = 0.0225 and wR = 0.0702 for 3143 observed reflections with I > 2σ(I). 1 presents a crisscrossed layer with mutually orthogonal {Cd(nip)} chains aggregated by neutral m-N(7),N(9)-Hade connector. By contrast, 2 displays a linear chain with CdⅡ ions extended by bis-bidentate chelating-nip2–connectors, which are further assembled into a broad ribbon by N-H···N hydrogen-bonding interactions. Additionally, the two solid-state samples with comparable thermal stability exhibit favorable luminescent emissions at room temperature, suggesting their potential applications as fluorescence materials. 展开更多

Two 1D coordination polymers Cu2I(C6N3H4)2(1) and CuⅡ(C6N3H4)2·H2O(2) based on benzotriazole(Bta) were hydrothermally synthesized by controlling the crystallization temperature.Single-crystal X-ray diffraction(XRD) analyses reveal that compound 1 is a 1D tubular structure constructed from two types of 1D chains {―Cu―N=N―N―} n,where the Cu(I) ions adopt linear,triangular,and tetrahedral coordination modes to connect two types of Bta ligands via π-π interaction inside the tubular-like chain.For compound 2,the Cu(Ⅱ) ions assume a quadrilateral coordination mode linking to the Bta ligands to give 1D straight chains,which stacks through π-π interactions to construct a 2D layer structure.Further characterizations including elemental analyses,infrared IR spectra,thermogravimetric(TG) analyses and luminescence properties have been done. 展开更多

ABSTRACT Four novel 1D lanthanide coordination polymers with formula [Ln(3,4-pybz)3(HzO)2. H2O]n (Ln = 1 Sm; 2 Eu; 3 Tb; 4 Dy, 3,4-Hpybz = 3-(pyridin-4-yl)benzoic acid) have been synthesized by hydrothermal reactions of lanthanide oxide and 3-(pyridine-4-yl) benzoic acid. Single-crystal X-ray diffraction shows that the four compounds are isostructural. They all crystallize in a monoelinic system, space group P1^-. They have a doubly carboxylate-bridged infinite-chain structure with alternating Ln-(carboxylate)2-Ln linkages and one chelating carboxylate group on each metal center. The Ln ion also combines to two water molecules to form an eight-coordinate square antiprismatic geometry. The pyridine nitrogen atoms of the ligand do not coordinate to the metal centers but direct the formation of a 3D network through hydrogen bonding with coordinated water molecules. The photoluminescent properties of 2 and 3 have been also studied. 展开更多

The creation of a porous magnet is a long-sought academic goal since magnetism and porosity are hostile to one another. While long-range magnetic ordering needs spin carriers of short separation through short bridges, porosity relies on the use of extended connecting ligands. Here, we will give a survey of the cluster-based magnetic porous coordination polymers, i.e., 0-D MPCPs, according to their functional subunits: (1) nanoporous spin crossover materials with single metal nodes; (2) metal-radical approach with rigid organic radical ligands and single metal nodes; (C) PCPs with rigid organic ligands and metal oligomer nodes; (D) PCPs with metal complex linkers and polymetal cluster nodes; (E) PCPs with organo-polymetal cluster linkers and single metal nodes. The assembly from clusters can provide a reasonable route to resolve the hostility between magnetism and porosity. This assembly’s merits are obvious: the pore benefits from the big cluster according to "Scale Chemistry", and the functional framework inherits interesting physical properties from the clusters with a large ground spin S. 展开更多

Three lanthanide coordination polymers [Ln(bcpb)0.5(NO3)(DEF)2] (Ln = Y (1), Tb (2), Eu (3), H4bcpb = 2,5-bis(2,4-dicarboxyphenyl) pyridine and DEF = N,N-diethylformamide)) have been solvothermally sy... Three lanthanide coordination polymers [Ln(bcpb)0.5(NO3)(DEF)2] (Ln = Y (1), Tb (2), Eu (3), H4bcpb = 2,5-bis(2,4-dicarboxyphenyl) pyridine and DEF = N,N-diethylformamide)) have been solvothermally synthesized under hydrothermal conditions with a novel Hnbcpb ligand and trivalent lanthanide nitrates. Single-crystal X-ray diffraction analysis reveals that compounds 1-3 are isostructural and crystallize in the monoclinic system, space group P21/n. Crystal data for 1: C20H26N409Y, Mr = 555.36, a = 13.022(9), b = 17.778(12), c = 10.861(8) A, β= 100.208(3)°, V = 2475(3) A3, Z = 4; Crystal data for 2: C20H26N4OgTb, Mr = 625.37, a = 13.0476(4), b = 17.8037(7), c = 10.9398(3) A, β = 100.008(4)°, V = 2496.4(12) A3, Z = 4; Crystal data for 3: C20H26N409Eu, Mr = 618.41, a = 13.055(4), b = 17.833(5), c = 10.893(3)A, β = 100.133(4)°, V= 2496.4(12) A3, Z = 4. The compounds were characterized by thermogravimetric analysis (TGA), IR spectroscopy, and X-ray single-crystal diffraction. Compounds 1-3 all feature 2D networks with -ABAB- fashions. The luminescent properties of compounds 1-3 and free H4bcpb ligand were investigated at room temperature. The results show that the H4bcpb ligand can efficiently transfer energy to the Tb(III) ions, while the energy is not fully transferred from the H4bcpb ligand to the Eu(III) ions. 展开更多

The assembly reactions of o- (or m-, or p-) tetrafluorobenzenedicarboxylic acid (denoted as o-H2L, m-H2L and p-HzL, respectively), benzonitrile and Ag+ ion led to three compounds: [Ag2(PhCN)2(o-HL)2]n (1), [Ag2(PhCN)2(m-HL)2]n (2) and [Ag2(PhCN)2(p-L)], (3). 1 and 2 feature a 1D coordination chain, while 3 bears a 2D net structure. A variety of weak interactions are observed in the compounds. Strong nwrinteractions connect the 1D chains into a 3D supramolecular network in 1. Hydrogen bonds connect the chains into layers in 2. Three types of interesting π-π interactions also assemble the 2D layers into a 3D overall structure in 3. 展开更多

Two new cadmium(II) and zinc(II) coordination polymers, {[Cd(btre)0.5- (mip)(H2O)2]·H2O}n (1) and [Zn(btre)(mip)]n (2), were synthesized at room temperature condition and characterized by IR spectra, elemental analyses, single-crystal and powder X-ray diffractions (btre = 1,2-bis(1,2,4-triazol-4-yl)ethane, H2mip = 5-methyl-1,3-benzenedicarboxylic acid). Complex 1 belongs to the triclinic system, P space group, with a = 8.9830(6), b = 10.0579(6), c = 10.2479(9) , α = 98.837(6), β = 115.975(8), γ = 106.370(6)°, V = 756.30(11) 3 and Z = 2; complex 2 crystallizes in monoclinic, space group P21/c, with a = 7.0332(3), b = 14.9947(7), c = 15.9689(7) ?, β = 97.1170(10)°, V = 1671.12(13) ?3 and Z = 4. Compounds 1 and 2 based on the same N/O-donor ligands show different structures. The one-dimensional chains of 1 are further linked by hydrogen bonding and π-π interactions to yield a three-dimensional supramolecular structure. The two-dimensional (6,3) networks of 2 are further extended into a 3D framework via π-π interactions. Thermal stabilities and luminescence of 1 and 2 were investigated. 展开更多
