摘要

摘要以六水氯化钴（II）、氢氧化钠、琥珀酸和异烟酰胺为原料，在甲醇水溶液中合成了一种新型的一维配位聚合物，[Co(suc)(ina)2(H2O)2]n （suc =琥珀酸盐，ina =异烟酰胺），[μ-succinatobis(isonicotinamide-κN) diaquacobalt (II)]。利用单晶x射线衍射、红外光谱和热分析对Co（II）进行了结构表征，结果表明Co（II）具有八面体配位几何结构，琥珀酸盐桥接钴中心形成一维聚合物链。广泛的氢键稳定了三维超分子结构。

Synthesis, Structural Characterization, and Supramolecular Assembly of a One-Dimensional Cobalt(II) Coordination Polymer with Succinato and Isonicotinamide Ligands

A novel one-dimensional coordination polymer, catena-poly[μ-succinatobis(isonicotinamide-κN)diaquaco-balt(II)], [Co(suc)(ina)₂(H₂O)₂]_n (suc = succinate, ina = isonicotinamide), was synthesized via the reaction of cobalt(II) chloride hexahydrate, sodium hydroxide, succinic acid, and isonicotinamide in aqueous methanol. Structural characterization using single crystal X-ray diffraction, FTIR spectroscopy, and thermal analysis revealed that Co(II) exhibits an octahedral coordination geometry, with succinate bridging the cobalt centers to form a one-dimensional polymeric chain. Extensive hydrogen bonding stabilizes the three-dimensional supramolecular architecture.
