Syntheses,Crystal Structures and Electrochemical Behaviors of Two Co(Ⅱ) Complexes with N-2-Pyrimidinyl-4-amino-benzenesulfonamides

水热法合成两种新的Co(Ⅱ)化合物[Co(SD)2(2,2′-bpy)](1)和{[Co(SD)2(4,4′-bpy)]·4H2O}n(2)(SD=N-2-嘧啶基-4-氨基苯磺酰,2,2′-bpy=2,2′-联吡啶,4,4′-bpy=4,4′-联吡啶),并通过元素分析、红外光谱、X射线粉末衍射、热重分析、循环伏安法进行结构和性能表征。单晶X-ray衍射分析表明化合物1是三斜晶系,空间群为P1;化合物2是单斜晶系,空间群为C2/c。电催化实验发现化合物1和2对H2O2、HCHO都具有良好的电催化活性。

Two new Co（II） complexes, [Co（SD）2（2,2＇-bpy）] （1） and {[Co（SD）2（4,4＇-bpy）]-4H2O}n （2） （SD=sulfadiazine, 2,2＇-bpy=2,2＇-bipyridine, 4,4＇-bpy=4,4＇-bipyridine） have been synthesized through hydrothermal reaction and characterized by elemental analysis, IR, powder X-ray diffraction （PXRD）, thermogravimetric analysis （TGA） and cyclic voltammetry （CV）. Single crystal X-ray analysis reveals that compound 1 crystallizes in the triclinic system, space group P1- and compound 2 crystallizes in monoclinic crystal system, space group C2/c. It is found that these two compounds have electrochemical response behaviors for H202 and HCHO. CCDC： 977532, 1; 977531, 2.
