A new cobalt（Ⅱ） polymer with quasi-rectangular cavities, [Co（L）2（TP）·H2O]n 1 （L=1-butylbenzimidazole, TP = terephthalate ion） has been prepared by means of self-assembly of 1-butylbenzimidazole, terephthalic acid and Co（NO3）2·6H2O. The structure of 1 was characterized by X-ray diffraction analysis. In the crystal packing, 2-D supramolecular layers are formed via π-π stacking interactions. The fluorescence emission spectra of L and 1 are described.

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.

One new coordination polymer, [Co4(H2 O)4(μ3-OH)2(atz)2(L)]n(1), was solvothermally prepared by the reaction of 3-amino-1,2,4-triazole(Hatz), 4,8-disulfonyl-2,6-naphthalenedicarboxylic acid(H4 L) and Co^(Ⅱ) salt. It crystallizes in monoclinic system, space group P21/c with a = 10.4454(7), b = 12.2214(8), c = 10.0818(7) ?, b = 102.284(7), V = 1257.56(15) ?~3, Dc = 2.325 g/cm^3, Mr = 880.24, Z = 2, F(000) = 880, μ = 2.859 mm^(-1), the final R = 0.0426 and wR = 0.0822 for 5526 observed reflections with I > 2σ(I). Structural analyses indicate that 1 exhibits a three-dimensional(3 D) pillared-layer framework with triazolate extended Co4^(Ⅱ) layers supported by rigid L^(4-) connectors. Magnetically, complex 1 displays strong spin-frustrated antiferromagnetism due to the triangular magnetic lattice and cooperative antiferromagnetic couplings mediated by quadruple heterobridges.

A novel mixed-ligand coordination polymer [Zn(BTA)(ip)0.5]n(1, HBTA = benzotriazole, H2 ip = isophthalic acid) has been synthesized under hydrothermal conditions, which was further characterized by X-ray diffraction, IR spectrum, elemental analysis and TG-DTA experiments. Complex 1 crystallizes in monoclinic system, space group Pnma with a = 8.9731(5), b = 22.0477(12), c = 10.0217(5) ?, V = 1982.66(18) ?3, Z = 8, C10 H6 ZnN3 O2, Mr = 265.55, Dc = 1.779 g/cm3, μ = 2.462 mm-1, F(000) = 1064, the final R = 0.0225 and wR = 0.0652 with I > 2σ(I). This complex is a 3 D framework with the(42,62,82)(4,62,83) topology. Furthermore, the thermal stability of complex 1 is observed to be dependent on the polymeric structure nature. Strong solid-state luminescence emissions suggest that complex 1 is a good candidate for light emission materials.

为研究猪附红细胞体的病原形态学特征及其致病特性,给6只临床健康小鼠成功感染了猪附红细胞体病,对试验组小鼠感染后的不同时期采集的血样进行了鲜血压片、姬姆萨染色及扫描电子显微镜下的形态学检查,红细胞计数和以P1:5′-GCATGCCCAGTCCCCAAGGA-3′和P2:5′-TGCGGGGAGTACGTGGGAAGG-3′为特异性引物,利用2003年LudwigE报道的方法对待检血样中附红细胞体DNA的PCR鉴定及测序。1000倍油镜下观察到单个或连成线状的附红细胞体附着于红细胞表面,红细胞变成刺状、菠萝状或"口"字形等不规则形状;12000倍扫描电镜下观察到了"逗点"状及以纤丝与红细胞膜相连的附红细胞体;红细胞计数结果显示:与对照组相比试验组小鼠在接种后第7、10、14天出现大量异型性红细胞,其中第10天严重变形红细胞数量最多。说明猪附红细胞体病发病明显期在感染后第7～14天,14d以后逐渐消散;PCR扩增得到782bp的DNA片段,经序列分析与序列号为AJ504999的相应片段同源性为99.74%。本试验为猪附红细胞体的病原特性的研究提供了科学依据,为猪附红细胞体病发病机理等方面更深入的研究奠定了基础。
