| 摘要: 采用溶剂热法合成了一种新型的钴（Ⅱ）基配合物，即{[Co（Hppc）2][Co2（4，4'-bipy）（H2O）4]（SO4）2·2H2O}n （1），其中H2ppc=5-（3-吡啶基）-1H-吡唑-3-羧酸，4，4'-bipy=4， 4'-联吡啶。配体H2ppc是由吡啶环、吡唑环和羧基共同组成，同时兼具了刚性和柔性。通过单晶X射线衍射对配合物1进行了结构测定。结果显示所合成的配合物1结晶在单斜晶系C2/c空间群，包括2个晶体学独立部分：二维层状[Co（Hppc）2]和一维链状[Co2（4，4'-bipy）（H2O）4]2-，并形成具有{44·62}{4}2拓扑网络结构的共晶化合物。此外，配合物1呈现出良好的电化学发光（ECL）性能以及良好的超级电容器性能。 |

| Abstract: A new cobalt(Ⅱ)-based complex, namely {[Co(Hppc)2][Co2(4, 4'-bipy)(H2O)4](SO4)2·2H2O}n (1) where H2ppc=5-(3-pyridyl)-1H-pyrazole-3-carboxylic acid and 4, 4'-bipy=4, 4'-bipyridine, was synthesized by solvothermal method. The ligand H2ppc is constituted by a pyridine ring, pyrazole ring, and carboxyl group, which possesses rigidity and flexibility. Complex1 was structurally determined by single-crystal X-ray diffraction and displays that the complex crystallizes in the C2/c pace group, monoclinic system. Complex1 includes two crystallographic independent parts which are 2D layered [Co(Hppc)2] and 1D chain like [Co2(4, 4'-bipy)(H2O)4]2- forming a co-crystal structure with a {44·62}{4}2 topological network. Furthermore, complex1 exhibits good electrochemiluminescence (ECL) performance and supercapacitive performance. |
