摘要
One new coordination polymer, [Mn(Hbtc)(bpy)(HO)]1, was synthesized by the reaction of manganese(Ⅱ) salt under pH-controlled hydrothermal conditions with unsymmetrical polycarboxylic acid of 1,2,4-benzenetricarboxylic acid(Hbtc) and 2,2?-bipyridine(bpy). The structure of complex 1 was characterized by single-crystal X-ray diffraction, IR spectra, powder X-ray analysis, thermal gravimetric analysis(TGA), UV-Vis spectrometry, photoluminescence and magnetic susceptibility. Complex 1 is a one-dimensional(1D) polymeric single-chain structure. Photoluminescence property is quite similar to the bpy ligand. Magnetic susceptibility measurement indicates that 1 shows a weak ferromagnetic coupling between the Mn~Ⅱ ions.
One new coordination polymer, [Mn(Hbtc)(bpy)(H_2O)_2]_n 1, was synthesized by the reaction of manganese(Ⅱ) salt under pH-controlled hydrothermal conditions with unsymmetrical polycarboxylic acid of 1,2,4-benzenetricarboxylic acid(H_3btc) and 2,2?-bipyridine(bpy). The structure of complex 1 was characterized by single-crystal X-ray diffraction, IR spectra, powder X-ray analysis, thermal gravimetric analysis(TGA), UV-Vis spectrometry, photoluminescence and magnetic susceptibility. Complex 1 is a one-dimensional(1D) polymeric single-chain structure. Photoluminescence property is quite similar to the bpy ligand.
