A new three-dimensional(3D) coordination polymer, [Cd(L)2H2O]n·5nH2O 1 with 4-[(3-pyridyl)methylamino]benzoate acid(HL), has been synthesized by slow evaporation solvent at room temperature, and structurally characterized by elemental analysis, IR spectrum, thermal analysis, fluorescence spectrum and single-crystal X-ray diffraction. Compound 1 crystallizes in the tetragonal system, space group I-4, with a = 20.7937(16), c = 13.515(2), V = 5843.5(11) 3, C26H34CdN4O10, Mr = 674.97, Dc = 1.534 g/cm3, μ(MoKα) = 0.808 mm-1, F(000) = 2768, Z = 8, the final R = 0.0276 and wR = 0.0691 for 5323 observed reflections(I 2σ(I)). The result of thermal analysis shows that 1 is stable under 290 ℃. Moreover, it exhibits blue photoluminescence at room temperature. 相似文献

磷化氢具有很强的杀虫性,使用方便,常用于仓储粮食杀灭成虫、幼虫和卵。又因磷化氢有剧毒,最高允许浓度为8.8×10~(-6)mol/m~3。由磷化氢引起的环境污染一直是采用高锰酸钾溶液吸收,比色法分析。该法操作复杂,费时,分析误差大,又对采样人员身体有害。本文用火焰光度检测器(FPD)分析无机化合物磷化氢。本法能直接检测空气样品,采样简单,分析速度快,灵敏度高。最小检测浓度为3×10~(-7)mol/m~3。 相似文献

Two new metal-organic coordination polymers [Co0.5(Heoba)(bib)0.5]2n(1) and [Cd(eoba)(phen)]n(2)(H2eoba = 4,4-(ethane-1,2-diyldioxy)dibenzoic acid, bib = 1,4-bis(imidazol-1-yl)-butane, phen = 1,10-phenanthroline) have been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, TG and single-crystal X-ray diffraction. Complex 1 is a 2D network structure, and complex 2 exhibits a 3D network structure. Moreover, the luminescent property of complex 2 has been investigated in the solid state. 相似文献
