摘要
利用简单步骤合成了酰胺类配体氮 -[双 ( 2 -吡啶 )甲基 ]吡啶 -2 -甲酰胺 ( L) ,在 2 5℃ ,I=0 .1 mol/ LKNO3的 3 0 %乙醇 -水溶液中用 p H滴定法测定了其与不同金属离子组成的二元和三元配合物的稳定常数 ,结合单晶结构讨论了物种的可能构型 ,并比较了配体与 Cu( )和 Fe( )形成配合物的热力学稳定性差异 。
N [Bis(2 pyridyl)methyl]pyridine 2 carboxamide was synthesized and characterized. At 25 ℃, I =0.1 mol/L KNO 3, the stability constants of the binary and ternary systems formed by the ligand with metal ions in ethanol aqueous solution were studied by pH titrations and the appropriate structures with respect to the titration species were proposed according to the literature and the obtained data. Furthermore we also investigated the thermodynamic stability difference between the copper and iron comp...
