Abstract The novel compound, [Co(ia)2(MeOH)2]·2MeOH was obtained from the reaction of stoichiometric amounts of cobalt(II) chloride and sodium 4-imidazoleacetate (ia) dissolved in anhydrous methanol. The compound has been characterized structurally by the X-ray, single crystal method. The imidazole ring N3 nitrogen and carboxylate oxygen atoms of the 4-imidazoleacetate ligands are binding sites to
摘要 将化学计量的氯化钴(II)与4-咪唑乙酸钠(ia)溶于无水甲醇反应,得到新型化合物[Co(ia)2(MeOH)2]·2MeOH。该化合物已通过 X 射线单晶方法进行结构表征。4-咪唑乙酸酯配体的咪唑环 N3 氮和羧基氧原子是金属离子的结合位点。其中两个配体和两个甲醇分子以中心对称的方式定位,将钴 (II) 配位球体形成为准八面体。在晶格中,复杂分子形成容纳溶剂分子的六边形通道。利用晶体的自发和热分解的红外示踪,
