Hydrothermal reaction of nickel acetate with 3-phosphonopropionic acid and 4,4′-bipyridine resulted in two novel phosphonate compounds Ni(HO3PC2H4COO)(4,4′-bpy)(H2O) · 0.5(4,4′-bpy) (bpy = bipyridine) (I) and Ni(O3PC2H4COOH)(4,4′-bpy)(H2O)3 · H2O (II). Single-crystal X-ray studies reveal that self-assemblies between the ligands and metal ion result in layer (I) and chain (II) structures. Magnetic measurement of I indicate there are ferromagnetic couplings between adjacent Ni2+ ions (C = 1.29 cm3 mol−1 K and θ = 2.25 K). 相似文献

Reaction of the nickel(II) macrocyclic complex 1 including pendant pentyl groups in MeCN/H2O mixed solvent with deprotonated cis,cis-1,3,5-cyclohexanetricarboxylic acid (CTC3 −) resulted in two-dimensional (2-D) coordination polymer [Ni(C18H42N6)]3[C6H9(COO)3]2·6H2O·6CH3CN (2). The crystal structure of 2 indicates that each nickel(II) macrocyclic unit binds two CTC3 − ions in trans position and each CTC3 − ion coordinates three nickel(II) macrocyclic complexes to form a 2-D layer with hexagonal motif. The dried solid of 2 differentiates MeOH, EtOH, and PhOH in toluene solvent with the Kf values of 1.38, 2.11, and 6.68 M− 1, respectively. 相似文献

Three manganese/4-sulfocalix[4]arene complexes, namely, {H[(C28H20O16S4)Mn(H2O)4Mn0.5(H2O)2]}n ·6nH2O (1), {NH4[(C28H20O16S4)Mn(H2O)4Mn0.5(H2O)2]}n · 5nH2O (2), [(C28H20O16S4)Mn2(H2O)8]n · 6nH2O (3), have been synthesized under different pH conditions. Complex 1, which exhibits a one-dimensional (1D) structure, is formed at [H+] = 2.0 mol L−1. Reaction at pH 4 leads to another one-dimensional (1D) coordination polymer of 2. At pH 5, a two-dimensional (2D) coordination polymer of complex 3 is formed, showing clearly structural effects on pH response. 相似文献

Two organic–inorganic hybrid compounds with the formula {[MnIII(Salen)(H2O)]4MoO4}·Cl2·16H2O (1) and {[MnIII(Salen)(H2O)]4WO4}·(CH3COO)2·11H2O (2) (Salen = Di-[2-hydroxyl-3-methoxyl-benzaldehyde] ethylenediamine) have been synthesized and structurally characterized by IR, UV–vis spectroscopy, TG analysis and single crystal X-ray diffraction. Structural analysis revealed that compounds 1 and 2 consist of a [MoO4]2 − or [WO4]2 − building unit and four {[MnIII(Salen)(H2O)]+ metal–organic moieties, respectively. In the crystal structure, the [MoO4]2 − or [WO4]2 − tetrahedra coordinated with four MnIII ions, resulting in the penta-nuclear heterometallic tetrahedra cluster compounds, which were rarely observed in the Mn-Salen system. Magnetic study revealed that there was antiferromagnetic coupling in the two compounds. 相似文献

C,N-intramolecularly coordinated germanium(IV) methoxides Ar3GeOMe (1) and (Ar′)2Ge(OMe)2 (2) [where Ar = [2-(Me2NCH2)C6H4]−, Ar′ = [2-(DipN = CH)C6H4]−, Dip = 2,6-(i-Pr)2C6H3] were prepared by the reaction of the lithium precursors ArLi and Ar′Li with Ge(OMe)4 in appropriate molar ratio. While the diorganogermanium(IV) compound 2 is air-stable specie, triorganogermanium(IV) compound is surprisingly smoothly hydrolyzed by air-moisture to corresponding triorganogermanol Ar3GeOH (3). Studied compounds were characterized by the help of multinuclear NMR spectroscopy and in the case of 2 and 3 using single-crystal X-ray diffraction analysis. 相似文献

A novel phosphonocarboxylic ligand, 4′-phosphonobiphenyl-3,5-dicarboxylic acid (H4pbpdc), was synthesized to construct 4 zinc compounds, namely, {[Zn3(pbpdc)2·2R}n (R = C5H12N for 1, C4H10N for 2 and C6H16N for 3) and {[Zn2pbpdc]·C6H18N3}n(4), which were characterized by X-ray crystallography, elemental analysis, FTIR and TG. Structures 1 ~ 3 have the same 3-dimensional (3-D) frameworks with point symbol of {4.6.73.8}2{42.6.72.8}2{42.62.7.8}2{42.62.72}. Structure 4 is constructed from a 6-connected metallic cluster and 3-connected phosphonocarboxylic building units resulting in a topology of flu-3,6-C2/c.

Three novel bismuth-based coordination polymers, [(CH3)2NH2][Bi(pdc)(bdc)]·2DMF, [(CH3)2NH2][Bi(tdc)2]·1.5DMF and [Bi(bpdc)2H2O]·xGuest (compounds 1–3) (H2pdc = 3,5-pyridinedicarboxylic acid, H2bdc = 1,4-benzenedicarboxylic acid, H2tdc = 2,5-thiophenedicarboxylic acid, H2bpdc = 4,4′-biphenyldicarboxylic acid), have been successfully synthesized under solvothermal conditions and characterized by single crystal X-ray diffraction. Compounds 1 and 2, which are constructed by 9-coordinated or 8-coordinated Bi3 +, feature three-dimensional structures with hms and dia topology, respectively. However, 5-coordinated Bi3 + based compound 3 is a two-dimensional layered structure. Compound 1 can tune emissive performance by doping different lanthanide ions Tb3 +, Eu3 + and Dy3 +. Furthermore, detection of nitro explosives is investigated. All of the compounds are characterized by elemental analysis, IR spectrum and thermogravimetric analysis. 相似文献

These compounds have cationic, neutral, and anionic frameworks, respectively. Topological analyses reveal that compound 2 has an hcb net, while compound 3 has a dia net. The photoluminescent property of compound 2 was also investigated. 相似文献

Two new sandwich-type germanotungstates K2H2{Zn(en)2}{Zn(en)2}2{(GeW9O34)2Zn4(Hen)2}·17H2O (1) and K2H2{Ni(en)2}{Ni(en)2}2{(GeW9O34)2Ni4(Hen)2}·12H2O (2) (en = ethylenediamine) have been hydrothermally synthesized. The polyanions of the two compounds are composed of a [Ge2W18M4(Hen)2O68]10? (M = Zn, Ni) group decorated by two [M(en)2(H2O)]2+ units. The luminescence of compound 1 exhibits an intense UV radiation emission maximum at λ ≈ 449 nm upon excitation of 372 nm. The magnetic investigation of compound 2 demonstrates the presence of ferromagnetic interactions between the Ni2+ ions of the Ni4O14(Hen)2 clusters in 2. 相似文献

The reaction between NiCO3 · Ni(OH)2, acrylic acid and ethylenediamine in a 2:4:1 molar ratio affords the binuclear complex, [Ni2(EDDP)2(H2O)2] · 2H2O 1. The organic ligand, EDDP2? (the dianion of the ethylenediamine-N,N-dipropionic acid ligand), results from the addition of one amine group to the carbon–carbon double bonds of two acrylato ions. The crystal structure of 1 consists of neutral centrosymmetric entities, with the nickel ions connected by two carboxylato groups, each one acting as a monoatomic bridge. The intramolecular Ni?Ni distance is 3.212 Å. The metal ions exhibit an octahedral geometry. The cryomagnetic investigation of 1 reveals an antiferromagnetic coupling of the nickel(II) ions (J = ?21.8 cm?1, H = ?JSNi1SNi2). 相似文献

Complex 1 displays a 3D structure with a Schläfli symbol of {44.62}{48.620}. Complex 2 possesses a 2D layer network, incorporating [Zn3(COO)6] second building units (SBUs), which is packed into a 3D supramolecular architecture by π ⋯ π interactions. Both of them exhibit strong luminescence characteristics. It is worth to note that complexes 1 and 2 show potential application to detect small organic molecules. 相似文献

A new organic-inorganic hybrid compound constructed from [Mn2V22O64]10 − units, H6[(C6H4NO2Cu(H2O)4)]2[Mn2V22O64]·28H2O 1, has been synthesized and characterized by single-crystal X-ray diffraction, IR, powder X-ray diffraction (XPRD) and TG. Compound 1 is composed of dimeric [Mn2V22O64]10 − polyoxoanions, metal-organo fragments [(C6H4NO2Cu(H2O)4)]2 + and lattice water molecules. Moreover, a three-dimensional supramolecular structure is formed in 1 by the extensive hydrogen bond interaction among the terminal oxygen atoms of [Mn2V22O64]10 − anions, the coordinated waters of Cu2 + ions and crystal water molecules. Compound 1 exhibits remarkable catalytic activity for the heterogeneous oxidation of sulfides under mild condition. 相似文献

The reaction of CuCl2·2H2O, diphenylphosphinomethane (dppm), and tetracyanoethylene (TCNE) affords one unexpected trinuclear copper(I) complex, [CuI3(dppm)3(μ3-Cl)2]·[TCMA] 1 (TCMA: tricyanoacrylmethylate, a new compound deriving from TCNE). Structural study shows that three copper atoms are connected by dppm ligands bridging each edge to form a Cu3P6 unit. At room temperature, 1 appears photoluminescence at 447 nm. And 1 also can electrocatalyze hydrogen generation from acetic acid with a turnover frequency (TOF) of 99.9 mol of H2 per mole of catalyst per hour at an overpotential of 941.6 mV. 相似文献

Two [M3L3]6 +-type organo-palladium(II) macrocyclic host molecules, {[(phen)Pd]3(4,7-phen)3}(NO3)6, 1·6NO3−; {[(dtod-phen)Pd]3(4,7-phen)3}(NO3)6, 2·6NO3−, (where M = (4,7-phen)Pd, (dtod-phen)Pd; 4,7-phen = 4,7-phenanthroline (L), phen = 1,10-phenanthroline, dtod-phen = 5,6-di(1′,4′,7′,10′-tetraoxododecanoxy)-1,10-phenanthroline), have been synthesized by metal-directed self-assembly in aqueous solution. These basket-shaped hosts bearing syn, syn, syn orientations and their anion complexes, have been fully characterized by 1H NMR, cold-spray ionization mass spectrometry (CSI-MS) and in the case of basket-shaped host 1*PF6− by X-ray single-crystal diffraction analysis. On the basis of anion binding structure within the cavity of 1, the molecule basket 2 possessing a hydrophobic inner cavity expanded with hydrophilic polyethyleneglycol chains was successfully designed for encapsulating one giant anion [(C2B9H11)2Co]− in water and the host–guest interaction was studied by 1H NMR titration and CSI-MS. 相似文献

An ether bridged tetracarboxylic acid ligand, 5-(3′,4′-Dicarboxylphenoxy)-isophthalic acid (H4L) was used to construct two Co(II) coordination polymers in presence of different nitrogen donor ligands such as 4,4′-bipyridine (4,4′-bpy) and 4,4′-bis(pyrid-4-yl)biphenyl (bpbp). The products formed under hydrothermal conditions are formulated as [Co2L(4,4′-bpy)2(H2O)3]n (1) and {[Co(bpbp)2(H2L)]·H2O}n (2). The compounds were characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis, and powder X-ray diffraction (PXRD) measurement. Compound 1 shows an intriguing (3,4,5)-connected 3D framework with a point symbol of (42 · 62 · 82)(42 · 65 · 83)(62 · 8). Compound 2 is an unusual 3D supramolecular framework generated by the one-dimensional [Co(bpbp)(H2L)]n polymer chain. The magnetic properties of compounds 1 and 2 were examined, indicating antiferromagnetic interactions between the cobalt(II) ions in the temperature range of 2–300 K. 相似文献
