1 INTRODUCTION Interest in metal phosphonate chemistry has in- creased in recent years, not only because of their rich structural chemistry[1~3] but also owing to their potential applications in catalysis, absorption and intercalation reaction[4~6]. The introduction of a se- cond metal-ligand component as a charge-compen- sating unit and structure-directing component into polyoxomolybdenum/oxovanadium organodi-phos- phonates has provided us a powerful method to syn- thesize this family o… 相似文献

采用水热法合成了一种新型多酸基无机-有机杂化材料{[Co(btp)(Hbtp)(H2O)3](PW12O40)·3H2O}n(1),并对化合物1进行了结构测定。X射线单晶衍射结果显示,Co(Ⅱ)离子通过btp配体连接形成一维链,[PW12O40]3-游离于相邻一维链相互交叉形成的孔隙中,从而扩展成三维结构。热重分析表明化合物1具有良好的热稳定性。此外,还对化合物1的质子导电性能进行了研究。结果表明,化合物1在358 K和98%RH条件下的质子电导率为6×10-5 S·cm-1。 相似文献

One new pillared layered zinc hydroxide {Zn_4(OH)_6(ndc)·2(H_2 O)}_n,(H_2 ndc =2,6-na-phthalenedicarboxylic acid) has been achieved under hydrothermal conditions by using2,6-na-phthalenedicarboxylic acid, 2,4-diami-6-phenyl-1,3,5-triazine as well as Zn(OAc)_2·2 H_2 O,and structurally characterized by X-ray single-crystal diffraction, IR spectra, elemental analysis,powder X-ray diffraction(PXRD) and thermogravimetric analysis(TGA). The X-ray single-crystal diffraction proves that the title compound is in monoclinic system, space group P2_1/c with a =16.362(8), b = 9.324(5), c = 5.364(3) ?, β = 99.081(9)°, V = 808.1(7) ?~3, D_c = 2.522 g/cm~3, M_r =613.73, Z = 2, F(000) = 608, μ = 5.935 mm~(-1), GOOF = 1.050, R = 0.0469 and wR(Ⅰ 2σ(Ⅰ)) =0.1291. In the title compound, the tetrahedral and octahedral zinc atoms are connected by μ_3-OH groups to form zinc hydroxide inorganic layers extending parallel to the bc-plane. The adjacent layers are pillared by the connection of Zn2 atoms with ndc~(2-)ligands to construct a three-dimensional(3D) structure; meanwhile, the interactions of five hydrogen bonds make the 3D network structure more stable. Furthermore, the title compound exhibits luminescent property at solid state. 相似文献

建立了一种合成碳负载型金纳米颗粒(AuC)的新方法.将酵母菌、葡萄糖及HAuCl4溶液混合后置于恒温摇床中,在310K下振荡数天得到酵母菌吸附的金前体盐(AuY);将AuY在氮气气氛中1 273K下煅烧得到AuC.采用扫描电镜和透射电镜观察了AuC的形貌;将AuC修饰在玻碳电极上并用于多巴胺的电化学检测.结果表明,AuY培养3d后,其酵母菌颗粒粒径分布不均匀,这主要是由于大量葡萄糖的吸附和包裹以及酵母孢子的存在所致;而AuY培养6d后得到的金颗粒粒径分布均匀,粒径约为10nm.此外,AuC在多巴胺电化学检测中具有非常好的响应,且检出限较低,其电化学过程为混合动力学控制过程. 相似文献

1 INTRODUCTION Transition-metal complexes supported by poly-dentate phosphine ligands have been widely studieddue to the unique photophysical properties andpotential applications as industrial catalysts, mole-cular sensors and drugs[1~3]. As known, oxidation ofphosphine ligands could happen in the synthesisreaction to result in novel complex with unexpectedstructure[4, 5]. For example, the structure of complexFe((OPPh2)2N)3[6] is an octahedral tris-chelate arrange-ment of the oxidized a… 相似文献
