A new 3D Ag（I） coordination polymer {[Ag（AZDB）（0.5）（bpe）（0.5）]·H2O}n（1） has been papared by azobenzene-3,3？-dicarboxylicate（H2AZDB）, 1,2-bis（4-pyridyl）ethylene（bpe） and silver salts via hydroth...A new 3D Ag（I） coordination polymer {[Ag（AZDB）（0.5）（bpe）（0.5）]·H2O}n（1） has been papared by azobenzene-3,3？-dicarboxylicate（H2AZDB）, 1,2-bis（4-pyridyl）ethylene（bpe） and silver salts via hydrothermal method. The compound was fully characterized by single-crystal X-ray diffraction, elemental analyses, infrared spectrum（IR）, powder X-ray diffraction（PXRD） and thermogravimetric analysis（TGA）. The strucrural analysis indicate that compound 1 shows a 3D pillared-layer framework constructed from a unique 1D Ag2O2 ribbon and pyridyl/carboxylicate mixed system, which features a 2-nodal（4, 6）-connected fsc net with a（4^4·6^10·8）（4^4·6^2） topology.Moreover, the photoluminescent properties have also been discussed.展开更多
A new Dy-based coordination polymer, namely {[Dy（cptpy）_2（H_2O）_2]（TPT）（Cl）}_n（1, Hcptpy = 4-（4-carboxyphenyl）-4,2？：6？,4？？-terpyridine, TPT = 2,4,6-tri（4-pyridyl）-1,3,5-triazine, DMA = N,N-dimethylac...A new Dy-based coordination polymer, namely {[Dy（cptpy）_2（H_2O）_2]（TPT）（Cl）}_n（1, Hcptpy = 4-（4-carboxyphenyl）-4,2？：6？,4？？-terpyridine, TPT = 2,4,6-tri（4-pyridyl）-1,3,5-triazine, DMA = N,N-dimethylacetamide） has been solvothermally synthesized by the reactions of DyCl_3, Hcptpy and TPT in a mixture solvent of DMA and H_2O. Single-crystal X-ray structural analysis reveals that 1 is a 1D linear chain coordination polymer with quadrangle channels which are occupied by the TPT ligands. The compound has been characterized by singe-crystal analyses, thermogravimetry analyses and powder X-ray diffraction measurements. The antitumor activity of compound 1 and its corresponding organic ligands Hcptpy and TPT were then investigated against four human lung cancer cell lines（NCI-H460, Calu-3, A549 and NCI-H292） by MTT assay. It was found that compared with Hcptpy and TPT, compound 1 exerted rather potent activity against all of these cell lines.展开更多
