N-(pyridine-3-sulfonyl amino)-acetate (H2L) in ethanol, water and 4,4′-Bipy under solvothermal conditions leads to the formation of a dinuclear copper polymer [Cu2(L)2(4,4′-Bipy)(H2O)2] · H2O · CH3OH} n (I). The polymer was characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis, and X-ray single-crystal diffraction (CIF file CCDC no. 1543747). The results showed that polymer
在溶剂热条件下,CuCl 2 ·2H 2 O与N-(吡啶-3-磺酰基氨基)-乙酸盐(H 2 L)在乙醇,水和4,4'-Bipy中的反应导致形成双核铜聚合物[Cu 2(L)2(4,4'-Bipy)(H 2 O)2 ]·H 2 O·CH 3 OH} n(I)。通过元素分析,红外光谱,热重分析和X射线单晶衍射(CIF文件CCDC 1543747)对聚合物进行了表征。结果表明聚合物属于三斜晶系\(P \ bar 1 \) 空间群。TG曲线表明,聚合物I首先除去水分子,然后配体分裂为聚合物I,剩余的残基为CuO。磁性测量显示N-(吡啶-3-磺酰基氨基)-乙酸盐为桥配体可介导磁性中心之间的反铁磁耦合相互作用。
