although complexes 1 and 2 were both binuclear, their Ag(I) centers exhibited different coordination geometric structures: four-coordinated distorted tetrahedron in complex 1, whereas three-coordinated planar triangle in complex 2. The electrochemical sensing performances of carbon paste electrode modified with Ag(I) complexes (CPE-1 for complex 1 and CPE-2 for complex 2) toward H2O2 were evaluated by cyclic
两种新的银 (I) 配合物,表示为 [Ag 2 L 1 2 (间苯二甲酸酯)]·(C 2 H 5 OH) 5 (1) , [Ag 2 L 2 2 (间苯二甲酸酯)] (2) (L 1 = 采用挥发法合成1,3-双[(N-甲基-苯并咪唑)亚甲基]-2-苯胺,L 2 = 1,3-双[(N-乙基-苯并咪唑)亚甲基]-2-苯胺),通过 X 射线晶体学、元素分析、IR 和 UV/Vis 光谱学进行表征。晶体分析表明,虽然配合物1和2都是双核的,它们的Ag(I)中心表现出不同的配位几何结构:配合物1中的四配位扭曲四面体,而配合物2中的三配位平面三角形。通过循环伏安法和计时电流法在 0.2 M 磷酸盐缓冲盐水中评估了用 Ag(I) 配合物修饰的碳糊电极(配合物 1 为 CPE-1,配合物2为 CPE- 2)对 H 2 O 2的电化学传感性能( PBS, pH = 6.0) at -0.2 V. 结果表明,CPE-1
