	Abstract:Three novel complexes, Zn(BDC-Cl4)(C5H5N)3(1), Cu(BDC-Cl4)(C5H5N)3(2) and Cd(BDC-Cl4)(C5H5N)3(3) (BDC-Cl4 = 2,3,5,6-tetrachloro-1,4-benzenedicarboxylate, tetrachloroterephthalate) have been synthesized. Complexes were characterized by X-ray single crystal diffraction, elemental analyse, FT-IR and thermogravimetric analysis. Complex 1 and 2 have been obtained by solvothermal method. Both of them have a five-coordination geometry with two monodentate tetrachloroterephthalate ligands and three pyridine molecules coordinated to the Zn(II) or Cu(II) ion center. The monodentate tetrachloroterephthalate bridge the adjacent Zn(II) or Cu(II) centers to lead to zig-zag chains. Complex 3 have also been gained by slow solvent diffusion. Each Cd(II) atom is six-coordinated to three carboxylate oxygen atoms and three pyridyl nitrogen atoms. Two type of tetrachloroterephthalate ligand, monodentate and bidentate carboxylate, connects Cd(II) center form zig-zag chains. Thermogravimetric analysis indicate that the mass loss of ligand starts at 240, 220 and 250 ℃ for complex 1, 2 and 3 respectively.

	Abstract: Two novel 1D compounds {[Ag3(Hbptc)(bpa)2]•H2O}n (1) and [Ag2(H2bptc)(bpp)2]n (2) ( H4bptc = 3,3′,4,4′-benzophenonetetracarboxylic acid, bpa = 1,2-bis(4-pyridyl)ethane and bpp = 1,3-bis(4-pyridy)propane ) were synthesized and structurally characterized. The crystal structures of compounds exhibit two kinds of ladder-like chains based on linear or T-shaped coordination environment of Ag(I). Fluorescence spectra of compounds 1 and 2 indicate the unusual intensity of fluorescent emission upon photoexcitation which may be attributed to ligand-to-metal charge transfer and Ag−Ag interactions.

	Abstract:Structures, charge and spin density distributions as well as nucleus-independent chemical shifts (NICSs) of [Ni(dmit)2]2-,1-,0 series, along with the dmit2-,1-,0 (dmit = 2-thione-1,3-dithiole-4,5-dithiolate) ligands, are investigated with density functional (B3LYP/6-311+G*) method. Upon oxidation from [Ni(dmit)2]2- to [Ni(dmit)2]0, theoretically deduced bond length change can be well explained by the rule of bonding and antibonding characters and is in good accord with the experimental results. Dmit2- ligand has already been oxidized at the initial coodination to the Ni2+ ion. It is the dmit2- ligand, rather than the central nickel ion, that has been oxidized upon oxidization of the [Ni(dmit)2]2-,1- series. In another word, the concept of oxidation in [Ni(dmit)2]2-,1- should apply to the dmit ligands, more exactly, apply to all sulfur atoms but not to the Ni ion.

	Abstract:The morphology and magnetic properties of NiCuZn ferrite have been studied. The nano-sized particles were prepared by a molten salt method. The properties of the (Ni0.37-xCuxZn0.62)Fe2O4 (x=0.16~0.22) were investigated by X-ray diffraction(XRD), scanning electron microscope (SEM) and vibrating sample magnetometer (VSM) techniques. It was found that the additions of CuO could induce the increasing of particles size due to the structure tend to be normal Zn ferrite. The Curie temperature Tc increased with Cu2+ content in the range of x<10, and then decreasing rapidly. This can be ascribed to that the amount of Cu2+ ion in B site increasing， which resulted in the superexchange effect of A-B increasing in the range of X<10.

	Abstract:A new β-diketonate derivative, 3 - ( 4 , 4 , 4 - trifluorobutane - 1,3 - ditone ) - 9 - butyl carbazole, as ligand L1 was synthesized, and its corresponding Cu(I) complex CuL1(PPh3)2 were prepared by the reaction of Cu(NO3)2•3H2O with copper powder, the β-diketonate ligand and triphenylphosphine in the mixed solution of ethanol, THF and acetonitrile. The complex was characterized by IR, 1H-NMR, single-crystal X-ray diffraction analysis. The spectral properties of the ligand and its complex have been studied. The study reveal that the complex exhibits significant optical and thermostability properties.

	7. Solvothermal preparation of Cu2O/Cu crystalline particles

	Abstract:Cu2O/Cu crystalline particles were synthesized via solvothermal reaction using dodecyl sulfate sodium as surfactant and D-glucose as reducing agent at 140°C for 4h. The products were characterized by means of transmission electron microscopy (TEM) and X-ray diffraction (XRD). The different morphologies of Cu2O/Cu crystals such as spherical and cubic can be obtained simply by adjusting the composition of the reaction system. For example, if small amounts of water was added in a mixture of Cu(NO3)2 and ethanol, the cubic morphology crystals could be formed. Moreover the ratio of water/ ethanol played a crucial role in fine tuning the structure and size of as-prepared Cu2O/Cu nanocrystals.In this paper, the formation mechanism of obtained cubic and spherical Cu2O/Cu crystalline particles is discussed.

	Abstract:The title complex, [[Cd(Him)(OH-BDC)(H2O)2]•3H2O]n (1) (Him = imidazole, OH-H2BDC = 5-hydroxyisophthalic acid), was synthesized by liquid/liquid diffusion method at room temperature. The complex crystallizes in orthorhombic, space group P2(1)2(1)2(1), with a = 6.7160(7), b = 13.8055(14), c = 17.4205(18) Å, V = 1615.2(3) Å3, C11H18CdN2O10, Mr = 450.67, Dc = 1.853 g/cm3, μ = 1.407 mm−1, F(000) = 904, Z = 4, the final R = 0.0209 and wR = 0.0453 for 3211 observed reflections (I >2σ(I)). In the structure of 1, the OH-BDC ligands exhibiting bis-bidentate coordination mode bridge the adjacent Cd centers to form a one-dimensional helical chain and the second ligand Him acting as terminal ligands are attached to the helical chain. It is notable that a series of complicated hydrogen bonds (eg: N—H•••O, O—H•••O) exist in the structure, which link neighboring helices into a three-dimensional supramolecular architecture. An observed intense blue luminescence with an emission band peaking at 390 nm for 1 may resulted from ligand-to-metal charge transfer (LMCT).

	Abstract:A simple molten salts route has been developed to prepare the high-quality LaF3:Eu nanoplates with different doping levels (10%, 20% and 30%), and the sizes of products could be adjusted by simply changing the molar ratio of NH4F to Ln(NO3)¬3. With this molar ratio increasing, the size of as-prepared nanocrystals decreased clearly. The possible mechanism of the reaction in molten salts was discussed, and the reason that the molar ratio of the precursors influenced the particle size of nanocrystals was assumed based on the theory of LaMer. At the same time, the fluorescent properties of all the samples were studied at room temperature. The intensity of 5D0→7F0 and 5D0→7F1 varied with different Eu doping levels, and the relative intensity ratios of 5D0→7F2 to 5D0→7F1 transition (I610/I590) increased as the particle size of nanocrysts decreased.

	Abstract:A sensitive fluorescence enhancement system was developed for the determination of zinc (Ⅱ). The fluorescence intensity of the Tb-N-(2-Pyridinyl)ketoacetamide (PKA) system was greatly enhanced by the addition of triethylamine (Et3N) and zinc nitrate in the methanol solution. The excitation and emission wavelengths were 329 nm and 546 nm, respectively. Under optimal conditions, the fluorescence intensities varied linearly with the concentration of Zn2+ in the range of 8.0×10-7-5.0×10-6 M with a detection limit of 9.9×10-8 M.. The interferences of some substances were described. This method was applied to the determination of amounts of Zn2+ in soybean, rice, and wheat, respectively. The results showed that the proposed procedure is a high selective, simple, and rapid method to the determination of Zn2+ ion. The mechanism of fluorescence enhancement was also studied.
