摘要

在 30 0C 和 I=0.1M (NaCl)条件下，通过 pH 电位法研究了癸二酸二酰肼（L）与 Co2+ 和 Ni2+ 的二元质子配体和金属配体平衡。癸二酸二酰肼是一种脂肪族多齿二元配体，可通过长线性-(CH2)8-碳氢链末端的两个酰肼基团与金属离子结合。这使得配体既能形成单核，也能形成双核。我们使用 Miniquad-75 程序对获得的电位数据进行了化学计量分析。形成的复合物包括质子化形式（MLH、ML2H 和 ML2H2）和去质子化形式（MLH-1 和 ML2H-1），以及简单的非质子化 ML 和 ML2 类型。此外，还发现了 M2L 和 M2LH-1 型同双核物种的形成。

Chemical Modelling Potentiometric Study on the Complex Formation of Ditopic Sebacic Acid Dihydrazide with Co2+ and Ni2+in Aqueous Medium

Binary proton-ligand as well as metal-ligand equilibria of Sebacicdicarboxylic acid dihydrazide (L) with Co2+and Ni2+were studied by pH-potentiometric method at 30 0C and I=0.1M (NaCl). Sebacic acid dihydrazide is an aliphatic polydentate ditopic ligand that can bind metal ions through two hydrazide groups present at the ends of a long linear –(CH2)8- hydrocarbon chain. This enables the ligand to form both mononuclear and binuclear species. The potentiometric data acquired were analysed chemometrically using the Miniquad-75 program. The complexes that converged include protonated (MLH, ML2H and ML2H2) and deprotonated forms (MLH-1 and ML2H-1) along with the simple unprotonated ML and ML2 types. The formation of homo-binuclear species of type M2L and M2LH-1 was also noticed.
