合成了超分子化合物[Co(HL)(2,2′-bipy)2]·9·5H2O(H3L=对羧基苯磺酰甘氨酸,2,2′-bipy=2,2′-联吡啶),并通过单晶X射线衍射确定了晶体结构,晶体结构分析表明化合物C29H42CoN5O15.5S属单斜晶系,C2/c空间群。Co(Ⅱ)离子为6配位的八面体结构,对羧基苯磺酰甘氨酸作为双齿配体与Co(Ⅱ)离子配位,2,2′-联吡啶和Co(Ⅱ)离子双齿螯合配位。配合物通过氢键和π-π堆积作用形成三维结构,配合物中含有一个由18个水分子组成的独立水簇。在氮气气氛中对该化合物进行了热重分析,结果表明:该化合物在30.1℃时开始失重,440℃时分解完全。
Supramolecular compounds [Co (HL) (2,2’-bipy) 2] · 9 · 5H2O (H3L = p-carboxybenzenesulfonylglycine and 2,2’-bipy = 2,2’-bipyridyl) The crystal structure was confirmed by single crystal X-ray diffraction. The crystal structure analysis showed that the compound C29H42CoN5O15.5S belongs to the monoclinic and C2 / c space group. The Co (Ⅱ) ion is a 6-coordinated octahedron with a p-carboxybenzenesulfonylglycine as a bidentate ligand that coordinates with the Co (Ⅱ) ion. 2,2’-dipyridyl and Co Co-bit. The complex forms a three-dimensional structure through hydrogen bonding and π-π stacking, and the complex contains a single water cluster consisting of 18 water molecules. Thermogravimetric analysis of this compound in a nitrogen atmosphere showed that the compound started to lose weight at 30.1 ° C and was completely decomposed at 440 ° C.
